drm/amd/pm: Add support to set min ISP clocks
Add support to set ISP clocks for SMU v14.0.0. ISP driver
uses amdgpu_dpm_set_soft_freq_range() API to set clocks via
SMU interface than communicating with PMFW directly.
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
and amdgpu_smu interfaces.
