drm/amd/pm: parse pp_handle under appropriate conditions

Browse source

amdgpu_dpm_is_overdrive_supported is a common API across all
asics, so we should cast pp_handle into correct structure
under different power frameworks.

v2: using return directly to simplify code
v3: SI asic does not carry od_enabled member in pp_handle, and update Fixes tag
