[PATCH] drm/amd/pm: parse pp_handle under appropriate conditions

[Guchun Chen]

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.

Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2541
Fixes: ebfc253335af("drm/amd/pm: do not expose the smu_context structure used internally in power")
