drm/amd: Add a new helper for loading/validating microcode
All microcode runs a basic validation after it's been loaded. Each
IP block as part of init will run both.
Introduce a wrapper for request_firmware and amdgpu_ucode_validate.
This wrapper will also remap any error codes from request_firmware
to -ENODEV. This is so that early_init will fail if firmware couldn't
be loaded instead of the IP block being disabled.
