[PATCHv2 00/12] arm/arm64: Unify PSCI client support

[Mark Rutland]

This series unifies the 32-bit and 64-bit PSCI client code, moving the bulk of
the FW invocation and probing out to a common locaiton in drivers/firmware.
As part of this, the remaining edge cases for PSCI 0.2 (Trusted OSs rejecting
CPU_OFF) are accounted for, maknig both 32-bit adn 64-bit clients more robust.

This results in a reasonable saving in terms of lines of code, and will allow
for PSCI 1.0 support to be unified form the beginning, avoiding further
duplication.

The series is based on v4.1-rc3.

Since v1 [1]:
* Fix build when PSCI isn't selected
* Don't indirect migrate_info_up_cpu
* Fix ver to u32 in psci_get_version

Thanks,
Mark.
