[PATCH v6 41/45] drm/amd: Use `amdgpu_ucode_*` helpers for GPU info bin

Mario Limonciello
2023-01-05T03:47:33Z

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 is for symmetry on unloading.
