37b9257be7 drm/amd/pm: Add VCN reset support check capability
This change introduces infrastructure to check whether VCN reset
is supported by the SMU firmware. Key changes include:

1. Added new functions to query VCN reset support:
   - amdgpu_dpm_reset_vcn_is_supported()
   - smu_reset_vcn_is_supported()
   - pptable_funcs.reset_vcn_is_supported callback

2. Implemented proper locking in the DPM layer with mutex protection

3. Maintained consistency with existing SDMA reset support checks

The new capability allows callers to check for VCN reset support
before attempting the operation, preventing unnecessary attempts
on unsupported platforms.

v2: clean up debug info(Alex)

amdgpu_dpm_set_soft_freq_range() is updated to take in any
pp_clock_type than limiting to support only PP_SCLK to allow
ISP and other driver modules to set the min/max clocks. Any
clock specific restrictions are expected to be taken care in
SOC specific SMU implementations instead of generic amdgpu_dpm

aperture address, it is not compatible with SMU and PSP, it need to be

d190e4d0f7 drm/amd/pm: add support for checking SDMA reset capability
This patch introduces a new function to check if the SMU supports resetting the SDMA engine.
This capability check ensures that the driver does not attempt to reset the SDMA engine
on hardware that does not support it.

The following changes are included:
- New function `amdgpu_dpm_reset_sdma_is_supported` to check SDMA reset
  support at the AMDGPU driver level.
- New function `smu_reset_sdma_is_supported` to check SDMA reset support
  at the SMU level.
- Implementation of `smu_v13_0_6_reset_sdma_is_supported` for the specific
  SMU version v13.0.6.
- Updated `smu_v13_0_6_reset_sdma` to use the new capability check before
  attempting to reset the SDMA engine.

v2: change smu_reset_sdma_is_supported type to bool (Tim)

e29dad86fa drm/amdgpu/swsmu: set workload profile to bootup default
Now that we can select a workload profile dynamically when
we submit work, it's best to default to the bootup
default workload profile.  Defaulting to other profiles
prevents some power management features from kicking in
during idle periods.  Once all jobs have finished, the
workload profile will automatically move back to default
bootup for max power savings.
