From: Igor Opaniuk <igor.opaniuk at foundries.io>
1. Adds support for:
* PSCI_FEATURES, introduced in PSCI 1.0. This provides API
that allows discovering whether a specific PSCI function is implemented
and its features.
* SYSTEM_RESET2, introduced in PSCI 1.1, which extends existing
SYSTEM_RESET. It provides support for vendor-specific resets, providing
reset_type as an additional param.
2. PSCI sysreset driver is refactored to use new API.
3. do_reset cmd is extended, optional param added for providing type of
reset
