While the GuC firmware and the Xe driver are using VF identifier VFID(0) to represent the Physical Function, we should avoid using "VF0" name and use proper "PF" name in all user facing messages related to the Physical Function and use "VFn" name only when referrinf to the true Virtual Function. Add simple helper to get properly formatted function name based on the function number.
