[PATCH 2/2] drm/amdgpu/swsmu: handle VCN harvesting for VCN SMU setup

[Alex Deucher]

Check if VCN instances are harvested when controlling
VCN power gating and setting up VCN clocks.

Fixes: 1b592d00b4ac83 ("drm/amdgpu/vcn: remove manual instance setting")
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1743
