Adds support for:
- PSCI_FEATURES, which was introduced in PSCI 1.0. This provides API
that allows discovering whether a specific PSCI function is implemented and its features.
- SYSTEM_RESET2, which was introduced in PSCI 1.1, which extends existing
SYSTEM_RESET. It provides support for vendor-specific resets, providing reset_type as an additional param.
For additional details visit [1].
Implementations of some functions were borrowed from Linux PSCI driver code [2].

Applied to u-boot/master, thanks!
I'm seeing a build failure on stm32mp1 from this patch:
