drm/amd/display: Move setup_stream_attribute
[WHY]
If symclk RCO is enabled, stream encoder may not be receiving an ungated
clock by the time we attempt to set stream attributes when setting dpms
on. Since the clock is gated, register writes to the stream encoder fail.
[HOW]
Move set_stream_attribute call into enable_stream, just after the point
where symclk32_se is ungated.
Logically there is no need to set stream attributes as early as is
currently done in link_set_dpms_on, so this should have no impact beyond
the RCO fix.

drm/amd/display: Reduce Stack Usage by moving 'audio_output' into 'stream_res' v4
The function `dp_retrain_link_dp_test` currently allocates a large
audio_output array on the stack, causing the stack frame size to exceed
the compiler limit (1080 bytes > 1024 bytes).
v2: Move audio-related data like `audio_output` is kept "per pipe" to
manage the audio for that specific display pipeline/display output path
(stream). (Wenjing)
v3: Update in all the places where `build_audio_output` is currently
called with a separate audio_output variable on the stack & wherever
`audio_output` is passed to other functions

`dce110_setup_audio_dto()` (like `az_configure`, `wall_dto_setup`)

to centralize audio data per pipe.
v4: Remove empty lines before `build_audio_output`. (Alex)

As this warning happens early in clang's frontend, it does not realize
that due to the assignment of r to -EINVAL, program_imu_rlc_ram() is
never actually called, and even if it were, data would not be
dereferenced because size is 0.
Just initialize data to NULL to silence the warning, as the commit that
added program_imu_rlc_ram() mentioned it would eventually be used over
the old method, at which point data can be properly initialized and
used.

drm/amdgpu: Replace HQD terminology with slots naming
The term "HQD" is CP-specific and doesn't
accurately describe the queue resources for other IP blocks like SDMA,
VCN, or VPE. This change:
1. Renames `num_hqds` to `num_slots` in amdgpu_kms.c to better reflect
the generic nature of the resource counting
2. Updates the UAPI struct member from `userq_num_hqds` to `userq_num_slots`
3. Maintains the same functionality while using more appropriate terminology

drm/amdgpu: Add user queue instance count in HW IP info
This change exposes the number of available user queue instances
for each hardware IP type (GFX, COMPUTE, SDMA) through the
drm_amdgpu_info_hw_ip interface.
Key changes:
1. Added userq_num_instance field to drm_amdgpu_info_hw_ip structure
2. Implemented counting of available HQD slots using:
- mes.gfx_hqd_mask for GFX queues
- mes.compute_hqd_mask for COMPUTE queues
- mes.sdma_hqd_mask for SDMA queues
3. Only counts available instances when user queues are enabled
(!disable_uq)
v2: using the adev->mes.gfx_hqd_mask[]/compute_hqd_mask[]/sdma_hqd_mask[] masks
to determine the number of queue slots available for each engine type (Alex)
v3: rename userq_num_instance to userq_num_hqds (Alex)

drm/amdgpu/gfx8: reset compute ring wptr on the GPU on resume
Commit 42cdf6f687da ("drm/amdgpu/gfx8: always restore kcq MQDs") made the
ring pointer always to be reset on resume from suspend. This caused compute
rings to fail since the reset was done without also resetting it for the
firmware. Reset wptr on the GPU to avoid a disconnect between the driver
and firmware wptr.
Writing a string without delimiters (' ', '\n', '\0') to the under
gpu_od/fan_ctrl sysfs or pp_power_profile_mode for the CUSTOM profile
will result in a null pointer dereference.

For kernel compute queues, align the timeout with

with SR-IOV which already used a shorter timeout.
Additionally the longer timeout negatively impacts
