CSS: Implement support for NODE_HW_STATE
This patch implements CSS platform hook to support NODE_HW_STATE PSCI
API. The platform hook queries SCP to obtain CSS power state. Power
states returned by SCP are then converted to expected PSCI return codes.
Juno's PSCI operation structure is modified to use the CSS
implementation.
