To work around a DMC/Punit issue on ICL where the driver's
ICL_PORT_COMP_DW8/IREFGEN PHY setting is lost when entering/exiting DC6

Similarly the driver's PHY/DBUF/CDCLK settings should have been preserved

Up until now, a single shared GPU address space was used. This is not
ideal as there's no protection between processes and doesn't work for
supporting the same GPU/CPU VA feature. Most importantly, this will
hopefully mitigate Alyssa's fear of WebGL, whatever that is.
Most of the changes here are moving struct drm_mm and struct
panfrost_mmu objects from the per device struct to the per FD struct.
The critical function is panfrost_mmu_as_get() which handles allocating
and switching the h/w address spaces.
There's 3 states an AS can be in: free, allocated, and in use. When a
job runs, it requests an address space and then marks it not in use when
job is complete(but stays assigned). The first time thru, we find a free
AS in the alloc_mask and assign the AS to the FD. Then the next time
thru, we most likely already have our AS and we just mark it in use with
a ref count. We need a ref count because we have multiple job slots. If
the job/FD doesn't have an AS assigned and there are no free ones, then
we pick an allocated one not in use from our LRU list and switch the AS
from the old FD to the new one.

Our pin mapping tables for ICP and MCC currently only list the standard
GPIO pins used for various output ports. Even through ICP's standard
pin usage only utilizes pins 1, 2, and 9-12, and MCC's standard pin
usage only uses pins 1, 2, and 9, these platforms do still have GPIO
registers to address pins in the range 1-3 and 9-14. OEM's may remap
GPIO usage in non-standard ways (and provide the actual mapping via VBT
settings), so we shouldn't exclude pins on these platforms just because
they aren't part of the standard mappings.
TGP's standard pin tables contains all the possible pins, so let's
rename them to "icp" and use them for all PCH >= PCH_ICP. This will
prevent intel_gmbus_is_valid_pin from rejecting non-standard pin usage
that an OEM specifies via the VBT.
Note that this will cause pin 9 to be labeled as "tc1" instead of "dpc"
in debug messages on platforms with the MCC PCH, but that may actually
help avoid confusion since the text strings will now be the same on all
gen11+ platforms instead of being different on just EHL.
v2: Drop now-unused MCC_DDC_BUS_DDI_* names.
v3: We want to compare against INTEL_PCH_TYPE, not INTEL_PCH_ID.

This patch effectively reverts commit 912bbf7e9ca4 ("gpu: ipu-v3:
image-convert: Fix image downsize coefficients") and replaces it with a
different solution based on the preceding patches.
The previous fix tried to solve the problem of intermediate tile size
between IC downsizing and main processing sections not being limited to
1024 pixels by downsizing the input image to a smaller intermediate size
in the downsizing box filter. This causes unnecessary blurring,
especially for scaling factors close to 1.
Now that the seam position calculation makes sure that the 1024 pixel
intermediate tile size limit is not exceeded, calculate the number of
tiles from the maximum of intermediate size and output size and avoid
unnecessary downsizing.
Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

This fixes a failure to determine any seam if the output size is
exactly 1024 multiplied by the number of tiles in a given direction.
In that case an empty interval out_start == out_end is being passed
to find_best_seam, which looks for a seam out_start <= x < out_end.
Also reduce the interval for all but the left column / top row, to
avoid returning position 0 as best fit.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct mmp_path {
...
struct mmp_overlay overlays[0];
};
size = sizeof(struct mmp_path) + count * sizeof(struct mmp_overlay);
instance = kzalloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, overlays, count), GFP_KERNEL)
Notice that, in this case, variable size is not necessary, hence it
is removed.
