This will display the sizes of kenrel BO's bound to an open file, which are
otherwise not exposed to UM through a handle.
The sizes recorded are as follows:
- Per group: suspend buffer, protm-suspend buffer, syncobjcs
- Per queue: ringbuffer, profiling slots, firmware interface
- For all heaps in all heap pools across all VM's bound to an open file,
record size of all heap chuks, and for each pool the gpu_context BO too.
This does not record the size of FW regions, as these aren't bound to a
specific open file and remain active through the whole life of the driver.

The RK3588 specific implementation is currently quite limited in terms
of handling the full range of display modes supported by the connected
screens, e.g. 2560x1440@75Hz, 2048x1152@60Hz, 1024x768@60Hz are just a
few of them.
Additionally, it doesn't cope well with non-integer refresh rates like
59.94, 29.97, 23.98, etc.
Make use of HDMI0 PHY PLL as a more accurate DCLK source to handle
all display modes up to 4K@60Hz.

Replace the large switch statement with a look-up table when selecting
the mode index. Makes the code easier to read. The table is sorted by
resolutions; if run-time overhead from traversal becomes significant,
binary search would be a possible optimization.
The mode index requires a refresh-rate index to be added or subtracted,
which still requires a minimal switch. In the original code, some of
the indices did not contain this computation. Those cases would have been
equivalent to adding 0, so they are now all subsumed in the switch's
default branch.

ASTDP requires a mode index, depending on the resolution. Move the
look-up code from ast_dp_set_mode() into a separate helper. Inline
the rest of the function into its only caller. Rename the variable
names and register constants to match the programming manual.
As before, the mode-index lookup still happens during the update's
atomic commit. Right now, there's no way of doing it during the atomic
check. The lookup requires the VBIOS mode, which is not available at
the atomic check's invocation. At least warn now if the mode index
could not be found.

Mode lines are independent from hardware Gen or TX chip, so hide all
VBIOS mode tables in ast_vbios.c.
Move the look-up code for VBIOS modes from ast_vbios_get_mode_info()
to ast_vbios_find_mode(). The new look-up function respects the
supported-mode flags in struct ast_device. For example, if a device
does not have struct ast_device.support_fullhd set, the helper does
not return a valid mode for 1920x1080. Taking the supported-mode flags
into account allows for making the VBIOS tables the single reference
for validating and setting display modes against hardware capabilities.

VBIOS mode tables are terminated by an entry with a refresh rate of
0xff. The code is hard to read and fragile to use. Therefore create
an empty entry with AST_VBIOS_MODE_INVALID to terminate each mode list.
Stop at the invalid entry when searching for modes in the tables.
Instead of testing for refresh == 0xff, test with a helper function if
the mode's size and refresh have meaningful values.

The ast driver looks up supplied display modes from an internal list of
display modes supported by the VBIOS.
Do not use the crtc_-prefixed display values from struct drm_display_mode
for looking up the VBIOS mode. The fields contain raw values that the
driver programs to hardware. They are affected by display settings like
double-scan or interlace.
Instead use the regular vdisplay and hdisplay fields for lookup. As the
programmed values can now differ from the values used for lookup, set
struct drm_display_mode.crtc_vdisplay and .crtc_hdisplay from the VBIOS
mode.

The ast driver matches DRM display modes against an internal list of
modes supported by the VBIOS. Matching H/V sync flags between modes is
preferred, but optional. If sync flags are not matching, the driver
would program the VBIOS settings to hardware and let the display handle
the difference.
DRM modes are generated from attached displays or standard mode lines.
Therefore differences to the VBIOS modes are not just cosmetical, but
signal possible incompatibility with the display hardware.
Hence make matching H/V sync flags mandatory. If the VBIOS does not
support a certain mode, we should report it as unsupported. Note that
the VBIOS mode tables all appear to refer to standard modes.
(If sync flags really make no difference to the VBIOS, the ast driver
shouldn't match them in the first place.)
