[PATCH v6 18/45] drm/amd: Use `amdgpu_ucode_*` helpers for GFX11

Mario Limonciello
2023-01-05T03:46:12Z

The `amdgpu_ucode_request` helper will ensure that the return code for
missing firmware is -ENODEV so that early_init can fail.

The `amdgpu_ucode_release` helper will provide symmetery on unload.
