Add support for new functions, introduced in PSCI v1.1 spec [1] (all
are optional):
* SYSTEM_RESET2 - extends existing SYSTEM_RESET. It provides
architectural reset definitions and vendor-specific
resets.
* MEM_PROTECT - provides protection against cold reboot attacks,
by ensuring that memory is overwritten before it is
handed over to an operating system loader.
* MEM_PROTECT_CHECK_RANGE - used to check whether a memory range is
protected by MEM_PROTECT.
