drm/amdgpu/pm: fix UVD handing in amdgpu_dpm_set_powergating_by_smu()
UVD and VCN were split into separate dpm helpers in commit
ff69bba05f08 ("drm/amd/pm: add inst to dpm_set_powergating_by_smu")
as such, there is no need to include UVD in the is_vcn variable since
UVD and VCN are handled by separate dpm helpers now. Fix the check.
