[PATCH v7 36/45] drm/amd: Use `amdgpu_ucode_*` helpers for SDMA3.0

From: Mario Limonciello
Date: Thu Jan 05 2023 - 12:06:30 EST


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.
