Subject: [PATCH 0/7] drivers: firmware: psci: Some cleanup and refactoring

All of these patches have been sent earlier, but part of a bigger series [1].
Instead of waiting for that series to get reviewed and accepted, I have split
it up, such that these trivial independent cleanups can go in as a first step.

The only intentional function change, should be the last patch, where we start
checking if PSCI OSI mode is supported in the PSCI FW and print a message about
it, as that is quite useful information for the user/developer.

As there is a ARM/ARM64 "tree wide" change included, it would be nice if
this could go in already for v5.1-rc1, to set the foundation for the next cycle.
I know it's *really* late for that, but maybe Rafael can help take it via his
pm-tree, if all acks are received of course?

Kind regards
Ulf Hansson
