g4x+ sprites have an extra cdclk limitation listed for RGB formats.
For some random reason I chose to use cpp>=4 as the check for that.
While that does actually work let's deobfuscate it by checking
for !is_yuv instead. I suspect is_yuv didn't exist way back when
I originally write the code.
Also drop the duplicate comment.

Even if we're not doing downscaling we should account for
some of the extra dotclock limitations for g4x+ sprites. In
particular we must never exceed the 90% rule, and with RGB
that limits actually drops to 80%.
So instead of bailing out when upscaling let's clamp the
scaling factor appropriately and go through the rest of
calculation normally. By luck we already did the full
calculations for the 1:1 case.

TGL made stepping a litte mess, workarounds refer to the stepping of
the IP(GT or Display) not of the GPU stepping so it would already
require the same solution as used in commit 96c5a15f9f39
("drm/i915/kbl: Fix revision ID checks").
But to make things even more messy it have a different IP stepping
mapping between SKUs and the same stepping revision of GT do not match
the same HW between TGL U/Y and regular TGL.
So it was required to have 2 different macros to check GT WAs while
for Display we are able to use just one macro that uses the right
revids table.
All TGL workarounds checked and updated accordingly.
v2:
- removed TODO to check if WA 14010919138 applies to regular TGL.
- fixed display stepping in regular TGL (Anusha)

There seems to be a bit of confusing redundancy in a way, how
plane data rate/min cdclk are calculated.
In fact both min cdclk, pixel rate and plane data rate are all
part of the same formula as per BSpec.
However currently we have intel_plane_data_rate, which is used
to calculate plane data rate and which is also used in bandwidth
calculations. However for calculating min_cdclk we have another
piece of code, doing almost same calculation, but a bit differently
and in a different place. However as both are actually part of same
formula, probably would be wise to use plane data rate calculations
as a basis anyway, thus avoiding code duplication and possible bugs
related to this.
Another thing is that I've noticed that during min_cdclk calculations
we account for plane scaling, while for plane data rate, we don't.
crtc->pixel_rate seems to account only for pipe ratio, however it is
clearly stated in BSpec that plane data rate also need to account
plane ratio as well.
So what this commit does is:
- Adds a plane ratio calculation to intel_plane_data_rate
- Removes redundant calculations from skl_plane_min_cdclk which is
used for gen9+ and now uses intel_plane_data_rate as a basis from
there as well.
v2: - Don't use 64 division if not needed(Ville Syrjälä)
- Now use intel_plane_pixel_rate as a basis for calculations both
at intel_plane_data_rate and skl_plane_min_cdclk(Ville Syrjälä)
v3: - Again fix the division macro
- Fix plane_pixel_rate to pixel_rate at intel_plane_pixel_rate
callsites
v4: - Renamed skl_plane_ratio function back(Ville Syrjälä)
v5: - Don't precalculate plane pixel rate for invisible plane,
check for visibility first, as in invisible case it will
have dst_w and dst_h equal to zero, causing divide error.
v6: - Removed useless warn in intel_plane_pixel_rate(Ville Syrjälä)
- Fixed alignment in intel_plane_data_rate(Ville Syrjälä)
- Changed pixel_rate type to be unsigned int in

Now that the planes declare their minimum cdclk requirements properly
we don't need to check the cdclk in skl_max_scale() anymore. Just check
against the maximum downscale ratio, and move the code next to it's
only caller.

Various pixel formats and plane scaling impose additional constraints
on the cdclk frequency. Provide a new plane->min_cdclk() hook that
will be used to compute the minimum acceptable cdclk frequency for
each plane.
Annoyingly on some platforms the numer of active planes affects
this calculation so we must also toss in more planes into the
state when the number of active planes changes.
The sequence of state computation must also be changed:
1. check_plane() (updates plane's visibility etc.)
2. figure out if more planes now require update min_cdclk
computaion
3. calculate the new min cdclk for each plane in the state
4. if the minimum of any plane now exceeds the current
logical cdclk we recompute the cdclk
4. during cdclk computation take the planes' min_cdclk into
accoutn
5. follow the normal cdclk programming to change the
cdclk frequency. This may now require a modeset (except
on bxt/glk in some cases), which either succeeds or
fails depending on whether userspace has given
us permission to perform a modeset or not.
v2: Fix plane id check in intel_crtc_add_planes_to_state()
Only print the debug message when cdclk needs bumping
Use dev_priv->cdclk... as the old state explicitly

I forgot to update the g4x sprite scaling stride check when GTT
remapping was introduced. The stride of the original framebuffer
is irrelevant when remapping is used and instead we want to check
the stride of the remapped view.
Also drop the duplicate width_bytes check. We already check that
a few lines earlier.

There's a helper in drm_fourcc.h these days to check of we're dealing
with a two plane YUV format. Make use if it.
Also s/plane/color_plane/ in skl_plane_relative_data_rate() to reduce
the confusion.

Yf tiling was removed in gen-12, so do not expose Yf modifiers to user
space. Gen-12 display also is incompatible with pre-gen12 Y-tiled
CCS, so do not expose I915_FORMAT_MOD_Y_TILED_CCS.
v2: Rebase to carry forward recently added gen11 formats.

Everything about the file is about display, and mostly about types
related to display. Move under display/ as intel_display_types.h to
reflect the facts.
There's still plenty to clean up, but start off with moving the file
where it logically belongs and naming according to contents.
v2: fix the include guard name in the renamed file
