drm/amd/powerplay: add the interface for getting ultimate frequency v3

Browse source

add the get_dpm_ultimate_freq for supporting different swSMU.
-v2:
        Handle the unsupported clock type and read smc message failed case and return error code.
        Move the smu12 uclk frequency retrieved logic to renoir ppt.
-v3:
        Use goto clause to handle invalidate clk index.
        Add the limited tag for smu_get_dpm_uclk to avoid other likewise interface introduced.
