Some board manufacturers hardcode the EDID for the embedded
panel in the VBIOS. This EDID should be used when the panel
doesn't have a DDC.
For reference, see the legacy non-DC display code:
amdgpu_atombios_encoder_get_lcd_info()
This is necessary to support embedded connectors without DDC.

[Why]
Rapid vblank off is causing flip-done timeouts for NV3x and newer
family of GPUs that support more idle optimization features.
A proper fix requires further investigation. In lieu of it, let's
workaround it for now.

For NV3x and newer family of DGPUs, restore the old 5s vblank off timer.

For LNL+, odd source size and panning for YUV 422/420 surfaces is
supported. However, it requires the UV (chroma) surface Start X/Y and
width/height to be calculated as ceiling(half of Y plane value) rather
than floor.
The current code uses (>> 17) which combines the U16.16 fixed-point to
integer conversion (>> 16) with a divide-by-2 for chroma subsampling
(>> 1) into a single floor division. For odd Y plane values this
produces an off-by-one error in the UV plane offset.
On Android systems we see PLANE ATS fault when NV12 overlays are
used with odd source dimensions:
[ 126.854200] xe 0000:00:02.0: [drm:intel_atomic_setup_scaler [xe]] [CRTC:148:pipe A] attached scaler id 0.0 to PLANE:33

With Y plane width 1279:
floor(1279/2) = 639 (current)
ceil(1279/2) = 640 (required)
Introduce fp_16_16_div2() and fp_16_16_to_int_ceil() helpers to cleanly
separate the two operations: first halve the U16.16 fixed-point value
for chroma subsampling (staying in fixed-point domain), then convert
to integer with ceiling rounding.
v2: Use DIV_ROUND_UP(value, 1 << 17) to preserve sub-pixel precision
while making the ceiling division readable (Jani, Uma)
v3: Split into two helpers - fp_16_16_div2() for fixed-point division
by 2 and fp_16_16_to_int_ceil() for ceiling conversion to integer,
cleanly separating chroma subsampling from fixed-point to integer
conversion (Jani)

GA100 is a compute-only variant of GA102 that boots GSP-RM like a
Turing, although it also has its own unique requirements.
Now that all the pieces are in place, we can enable GA100 support.
Although architecturally like an Ampere, GA100 uses the same GSP-RM
firmware files as Turing, and therefore must boot it like Turing does.
However, as a compute-only part, GA100 has no display engine.

The GPU's ROM may begin with an Init-from-ROM (IFR) header that precedes
the PCI Expansion ROM images (VBIOS). When present, the PROM shadow
method must parse this header to determine the offset where the PCI ROM
images actually begin, and adjust all subsequent reads accordingly.
On most GPUs this is not needed because the IFR microcode has already
applied the ROM offset so that PROM reads transparently skip the header.
On GA100, for whatever reason, the IFR offset is not applied to PROM
reads. Therefore, the search for the PCI expansion must skip the IFR
header, if found.

window. GA100 is a special case in that although there is an
FRTS, its size must arbitrarily be set to 0.
Note that we cannot use supports_display() to determine the FRTS
size because there are other GPUs (e.g. GA102GL) that have display
disabled (and so supports_display() returns False), but the FRTS
window size still needs to be 1MB.

[Why]
A previous warning-fix commit updated type casts in the DCN3
mmhubbub code but missed updating the MCIF_ADDR macro to the
correct, fully parenthesized and casted version. This caused
a regression during DWB tests, where address values could be
misinterpreted, potentially leading to incorrect hardware
programming.
[How]
Updated the MCIF_ADDR macro in dcn30_mmhubbub.c to use the
proper parenthesization and type casting, ensuring correct
address handling. Removed redundant casts from REG_UPDATE
calls for improved clarity and consistency with current
coding standards.
