SCMI cleanups for v4.18

This contains all of the trivial review comments that were not
addressed as the series was already queued up for v4.17 and were not
critical to go as fixes.

They generally just improve code readability, fix kernel-docs, remove
unused/unnecessary code, follow standard function naming and simplifies
certain exit paths.
