[PATCH 1/4] drm/amdgpu/vcn3.0: handle harvesting in firmware setup

[Alex Deucher]

Only enable firmware for the instance that is enabled.

v2: use AMDGPU_UCODE_ID_VCN + i

[PATCH 2/4] drm/amdgpu: Consolidate VCN firmware setup code

[Alex Deucher]

Roughly the same code was present in all VCN versions.
Consolidate it into a single function.

v2: use AMDGPU_UCODE_ID_VCN + i, check if num_inst >= 2
