Below changes add a mechanism to reset GuC and retry fw loading if the initial load fails. There are cetain HW issues because of which fw load can fail and the WA is to retry after resetting GuC.
A patch required for engine reset is partially reused as we use that function to reset guc. v2: used updated engine reset helper function.
