Applied to arm64 (for-next/fw-rmi), thanks!

Rafael, I took the liberty of merging patch 7 below adding an arch
hibernation hook needed for arm64 (I changed the subject as well to
PM: ...).

For now the RMI is default off. We should only make it default y when we
have a deferred activation gated by kvm rmm option (or PCIe?).

There are a few typo fixes, some reordering of the Kconfig and Makefile
entries to preserve a somewhat alphabetical order. No functional change
though.
