When we sanitize planes let's wait for the scanout to stop
before we let the subsequent code tear down the ggtt mappings
and whatnot. Cures an underrun on my ivb when I boot with
VT-d enabled and the BIOS fb gets thrown out due to stolen
being considered unusable with VT-d active.

We tend to use output_format!=RGB as a shorthand for YCbCr, but
this fails if we have a disabled crtc where output_format==INVALID.
We're now getting some fail from intel_color_check() when we have:
hw.enable==false
hw.ctm!=NULL
output_format==INVALID
Let's avoid that by throwing INTEL_OUTPUT_FORMAT_INVALID to the
dumpster, and thus everything defaults to RGB when the crtc
is disabled.
This does beg the deeper question of how much of the state
should we in fact be validating when hw/uapi.enable==false.
And should we even be doing the uapi->hw copy when
uapi.enable==false? So far I've not been able to come up with
satisfactory answers for myself, so I'm putting it off for the
moment.

similar to the skl+ code. And just like skl/bxt/glk bdw also
needs the disable w/a, thus we need to plumb the desired state
of the async flip all the way down to i9xx_plane_ctl_crtc().
According to the spec we do need to bump the surface alignment
to 256KiB for this. Async flips require an X-tiled buffer so
we don't have to worry about linear.

Prevent the ICL HDR plane pipeline from performing YUV color range
correction twice when the input is in limited range. This is done by
removing the limited-range code from icl_program_input_csc().
Before this patch the following could happen: user space gives us a YUV
buffer in limited range; per the pipeline in [1], the plane would first
go through a "YUV Range correct" stage that expands the range; the plane
would then go through the "Input CSC" stage which would also expand the
range because icl_program_input_csc() would use a matrix and an offset
that assume limited-range input; this would ultimately cause dark and
light colors to appear darker and lighter than they should respectively.
This is an issue because if a buffer switches between being scanned out
and being composited with the GPU, the user will see a color difference.
If this switching happens quickly and frequently, the user will perceive
this as a flickering.

In order to make the dbuf state computation less fragile
let's make it stand on its own feet by not requiring someone
to peek into a crystall ball ahead of time to figure out
which pipes need to be added to the state under which potential
future conditions. Instead we compute each piece of the state
as we go along, and if any fallout occurs that affects more than
the current set of pipes we add the affected pipes to the state
naturally.
That requires that we track a few extra thigns in the global
dbuf state: dbuf slices for each pipe, and the weight each
pipe has when distributing the same set of slice(s) between
multiple pipes. Easy enough.
We do need to follow a somewhat careful sequence of computations
though as there are several steps involved in cooking up the dbuf
state. Thoguh we could avoid some of that by computing more things
on demand instead of relying on earlier step of the algorithm to
have filled it out. I think the end result is still reasonable
as the entire sequence is pretty much consolidated into a single
function instead of being spread around all over.
The rough sequence is this:
1. calculate active_pipes
2. calculate dbuf slices for every pipe
3. calculate total enabled slices
4. calculate new dbuf weights for any crtc in the state
5. calculate new ddb entry for every pipe based on the sets of
slices and weights, and add any affected crtc to the state
6. calculate new plane ddb entries for all crtcs in the state,
and add any affected plane to the state so that we'll perform
the requisite hw reprogramming
And as a nice bonus we get to throw dev_priv->wm.distrust_bios_wm
out the window.

To get sensible vblank timestamping behaviour we need to feed
the vmax based timings to the vblank code, otherwise it'll chop
off the scanline counter when it exceeds the minumum vtotal.
Additionally with VRR we have three cases to consider when we
generate the vblank timestamp:
1) we are in vertical active
-> nothing special needs to be done, just return the current
scanout position and the core will calculate the timestamp
corresponding to the past time when the current vertical
active started
2) we are in vertical blank and no push has been sent
-> the hardware will keep extending the vblank presumably
to its maximum length, so we make the timestmap match the
expected time when the max length vblank will end. Since
the timings used for this are now based on vmax nothing
special actually needs to be done
3) we are in vblank and a push has been sent so the vblank is
about to terminate
-> presumably we want the timestmap to accurately reflect
when the vblank will terminate, so we use the sampled
frame timestamp vs. current timestamp to guesstimate
how far along the vblank exit we are, and then we
adjust the reported scanout position accordingly so
that the core will see that the vblank is close to
ending.

On some platforms we need to trigger an extra async flip with
the async flip bit disabled, and then wait for the next vblank
until the async flip bit off state will actually latch.
Currently the w/a is just open coded for skl+ universal planes.
Instead of doing that lets reuse the .async_flip() hook for this
purpose since it needs to write the exact same set of registers.
In order to do this we'll just have the caller pass in the state
of the async flip bit explicitly.

Set up the async flip PLANE_CTL bit directly in the
.async_flip() hook. Neither .update_plane() nor .disable_plane()
ever need to set this so having it done by skl_plane_ctl_crtc()
is rather pointless.

Prepare for more platforms with async flip support by turning
the flip_done interrupt enable/disable into plane vfuncs.

Only assign the plane->async_flip() vfunc when the plane supports
async flips. For now we keep this artificially limited to the primary
plane since thats the only thing the legacy page flip uapi can target
and there is no async flip support in the atomic uapi yet.

There are two CSC on pipeline on gen11 and later platform.
User space application is allowed to enable CTM and RGB
to YCbCr coversion at the same time now.
v2: check csc capability in {}_color_check function.
v3: can't support two CSC at the same time in {ivb,glk}_color_check.

This pulls a large chunk of the pll calculation code out of
intel_display.c to a new file.
One function makes sense to be an inline, otherwise this
is pretty much a straight copy cover. Also all the
remaining hooks for g45 and older end up the same now.

We dropped the other redundant master_transcoder assignments
earlier, but this one slipped through. Get rid of it as well.
The crtc state gets fully reset before readout so there is
no point in doing this.
