ARM: migrate to common PSCI client code
Now that the common PSCI client code has been factored out to drivers/firmware, and made safe for 32-bit use, move the 32-bit ARM code over to it. This results in a moderate reduction of duplicated lines, and will prevent further duplication as the PSCI client code is updated for PSCI 1.0 and beyond. The two legacy platform users of the PSCI invocation code are updated to account for interface changes. In both cases the power state parameter (which is constant) is now generated using macros, so that the pack/unpack logic can be killed in preparation for PSCI 1.0 power state changes.
