drm/amd/pm: add get_dpm_ultimate_freq function for cyan skillfish
Some clients(e.g., kfd) query sclk/mclk through this function.
As cyan skillfish doesn't support dpm, for sclk, set min/max
to CYAN_SKILLFISH_SCLK_MIN/CYAN_SKILLFISH_SCLK_MAX(to maintain the
existing logic).For others, set both min and max to current value.
Before this patch:
# /opt/rocm/opencl/bin/clinfo
Max clock frequency: 0Mhz
After this patch:
# /opt/rocm/opencl/bin/clinfo
Max clock frequency: 2000Mhz
v2:
- Maintain the existing min/max sclk logic.(Lijo)
v3:
- Avoid fetching metrics table twice.(Lijo)
