Subject: 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.

Signed-off-by: Will Deacon <will.deacon@arm.com>
[Marc: s/u32/u64/ in the relevant spots, and switch from an initcall
 to an simpler init function]
