arm64: psci: add support for PSCI invocations from the kernel
This patch adds support for the Power State Coordination Interface
defined by ARM, allowing Linux to request CPU-centric power-management
operations from firmware implementing the PSCI protocol.

[Marc: s/u32/u64/ in the relevant spots, and switch from an initcall
to an simpler init function]
