Current code only supports usage cases with one pair of mixers at
most. To support quad-pipe usage case, two pairs of mixers need to
be reserved. The lm_count for all pairs is cleared if a peer
allocation fails in current implementation. Reset the current lm_count
to an even number instead of completely clearing it. This prevents all
pairs from being cleared in cases where multiple LM pairs are needed.

Compute more of the required FB layout information to boot the GSP
firmware.
This information is dependent on the firmware itself, so first we need
to import and abstract the required firmware bindings in the `nvfw`
module.
Then, a new FB HAL method is introduced in `fb::hal` that uses these
bindings and hardware information to compute the correct layout
information.
This information is then used in `fb` and the result made visible in
`FbLayout`.
These 3 things are grouped into the same patch to avoid lots of unused
warnings that would be tedious to work around. As they happen in
different files, they should not be too difficult to track separately.

Calls to xe_force_wake_put() should generally pass the exact reference
returned by xe_force_wake_get(). Since OA grabs and releases forcewake
in different functions, xe_oa_stream_destroy() is currently calling put
with a hardcoded ALL mask. Although this works for now, it's somewhat
fragile in case OA moves to more precise power domain management in the
future.
Stash the original reference obtained during stream initialization
inside the stream structure so that we can use it directly when the
stream is destroyed.

Align pitch to multiples of 8 pixels for bpp values that do not map
to RGB formats. The call to drm_driver_color_mode_format() fails with
DRM_INVALID_FORMAT in these cases. Fall back to manually computing
the pitch alignment from which drm_mode_size_dumb() can compute the
correct pitch.
Fixes userspace that allocates dumb buffers for YUV formats, where
bpp equals 12. A common example is the IGT kms_getfb test.

Instead of trying very hard to find the largest fair GGTT size that
could be allocated for VFs on the current tile, pick some smaller
rounded down to power-of-two value that is more likely to be
provisioned in the same manner by the other PF instance:
num VFs | GGTT space (MiB)
--------+-----------------
63..57 | 56
56..29 | 64
28..15 | 128
14..8 | 256
7..4 | 512
3..2 | 1024
1 | 2048 (regular PF)
1 | 3584 (admin only PF)
Note that due to FW/HW limitations we can't share all 4GiB GGTT
address space with VFs, so for the larger (>7) number of the VFs
the change in the outcome is happening at different points than
we have in case of GuC contexts/doorbells IDs.

so that all the platform specific details about cursors are
concentrated in one file.

Replace the hardcoded 256 with mode_config->cursor_width
when doing the cursor DDB allocation. Currently 256 is correct
for all SKL+, but this might change in the future. One less place
to change should that happen.

Replace the technically inaccurate drm_format_info() with the
accurate drm_get_format_info() in the SKL+ cursor DDB
allocation code.
Since we're only interested in the linear modifier here, the two
functions do actually return the same information. But let's not
use drm_format_info() to avoid setting a bad example.

Make the order of things a bit less fragile in
intel_framebuffer_init() by assigning 'ret' in each
error branch instead of depending on some earlier
assignment.

Use intel_fb_modifier_to_tiling() to convert the modifier into
the fence tiling mode during BIOS FB readout, rather than hand
rolling it. With this we can also stop tracking the tiling mode
in the intel_plane_config.

Use drm_get_format_info() instead of drm_format_info() to populate
fb->format during the BIOS FB readout. The difference being that
drm_get_format_info() knows about compressed formats whereas
drm_format_info() doesn't.
This doesn't actually matter in practice since the BIOS FB should
never be compressed, but no reason we shouldn't use the more accurate
function here anyway.

Pass the format info into plane->max_stride() from the
caller instead of doing yet another drm_format_info()
lookup on the spot.
drm_format_info() is both rather expensive, and technically
incorrect since it doesn't return the correct format info
for compressed formats (though that doesn't actually matter
for the current .max_stride() implementations since they
are just interested in the cpp value).
Most callers already have the format info available. The
only exception is intel_dumb_fb_max_stride() where we shall
use the actually correct drm_get_format_info() variant.
