[PATCH 1/2] drm/amd/pm: add get_dpm_ultimate_freq function for cyan skillfish

[Lang Yu <Lang.Yu@amd.com>]

Some clients(e.g., kfd) query sclk/mclk through this function.

Before this patch:
 # /opt/rocm/opencl/bin/clinfo

 Max clock frequency:                           0Mhz

After this patch:
 # /opt/rocm/opencl/bin/clinfo

 Max clock frequency:                           1500Mhz
