[Arun Siluvery]

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 from engine reset series (which are under review) is sneaked in
here as this changes reuses some of the functionality in that patch.
