This pull request contains patches that enable PSCI 1.0 firmware
features for arm/arm64 platforms:
- Lorenzo Pieralisi adds support for the PSCI_FEATURES call, manages
various 1.0 specifications updates (power state id and functions return
values) and provides PSCI v1.0 DT bindings
- Sudeep Holla implements PSCI v1.0 system suspend support to enable PSCI
based suspend-to-RAM
