soc: qcom: rpmh-rsc: remaining U-Boot API changes

Minor adjustments to fix building with U-Boot and work correctly as a
synchronous driver without interrupts. RPMh is fast enough that we can
get away with just firing off requests and assuming they complete.

U-Boot behaviour changes are annotated with a "U-Boot:" comment.
