Based on ufshci spec, it defines that "Offset C0h to FFh" belong
to vendor specific. If cpu vendor doesn't support these commands, it
makes the dme errors:
ufs: dme-set: attr-id 0xd041 val 0x1fff failed 0 retries
ufs: dme-set: attr-id 0xd042 val 0xffff failed 0 retries
ufs: dme-set: attr-id 0xd043 val 0x7fff failed 0 retries
Create a hook for unipro vendor-specific commands.
