Subject: drm/amd: Use `amdgpu_ucode_*` helpers for MES
From: Mario Limonciello <mario.limonciello@xxxxxxx>
commit 11e0b0067ec0707e8e598a5f9a547ab618ae7982 upstream.
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 provides symmetry for releasing firmware.
