drm/amdgpu: Add support for querying the max ibs in a submission. (v3)

This info would be used by radv to figure out when we need to
split a submission into multiple submissions. radv currently has
a limit of 192 which seems to work for most gfx submissions, but
is way too high for e.g. compute or sdma.

Userspace is available at
https://gitlab.freedesktop.org/bnieuwenhuizen/mesa/-/commits/ib-rejection-v3

v3: Completely rewrote based on suggestion of making it a separate query.

drm/amd/display: Block optimize on consecutive FAMS enables

[WHY]
It is possible to commit state multiple times in rapid succession with
FAMS enabled; if each of these commits were to set optimized_required,
then the user may see latency.

[HOW]
fw_based_mclk_switching is currently not used in dc->clk_mgr; use it
to track whether the current state has FAMS enabled;
if it has, then do not disable FAMS in prepare_bandwidth, and do not set
optimized_required.

[WHY]
Writing to DRR registers such as OTG_V_TOTAL_MIN on the same frame as a
pipe commit can cause underflow.

[HOW]
Move DMUB p-state delegate into optimze_bandwidth; enabling FAMS sets
optimized_required.

This change expects that Freesync requests are blocked when
optimized_required is true.

[WHY]
 Function "amdgpu_irq_update()" called by "amdgpu_device_ip_late_init()" is an atomic context.
 We shouldn't access registers through KIQ since "msleep()" may be called in "amdgpu_kiq_rreg()".

[HOW]
 Move function "amdgpu_virt_release_full_gpu()" after function "amdgpu_device_ip_late_init()",
 to ensure that registers be accessed through RLCG instead of KIQ.

drm/amdgpu: simplify amdgpu_ras_eeprom.c

All chips that support RAS also support IP discovery, so
use the IP versions rather than a mix of IP versions and
asic types.  Checking the validity of the atom_ctx pointer
is not required as the vbios is already fetched at this
point.

drm/i915: disable sampler indirect state in bindless heap

By default the indirect state sampler data (border colors) are stored
in the same heap as the SAMPLER_STATE structure. For userspace drivers
that can be 2 different heaps (dynamic state heap & bindless sampler
state heap). This means that border colors have to copied in 2
different places so that the same SAMPLER_STATE structure find the
right data.

This change is forcing the indirect state sampler data to only be in
the dynamic state pool (more convenient for userspace drivers, they
only have to have one copy of the border colors). This is reproducing
the behavior of the Windows drivers.

drm/amdkfd: Check PCIe atomics support on GFX11 to set CP_HQD_HQ_STATUS0[29]

CP_HQD_HQ_STATUS0[29] bit will be used by CPFW to acknowledge whether
PCIe atomics are supported. The default value of this bit is set
to 0. Driver will check whether PCIe atomics are supported and set the
bit to 1 if supported. This will force CPFW to use real atomic ops.
If the bit is not set, CPFW will default to read/modify/write using the
firmware itself.

This is applicable only to GFX11 RS64 CP with MEC FW >= 509. If MEC
FW < 509 and for all GFX11 F32 CP, PCIe atomics needs to be supported
else it will skip the device.

This commit also involves moving amdgpu_amdkfd_device_probe() function
call after per-IP early_init loop in amdgpu_device_ip_early_init()
function so as to check for RS64 enabled device.
