Bug Description
SRU Justification:
[Impact]
PSCI v1.3 adds support for SYSTEM_OFF2 which is analogous to ACPI S4 state.
This will allow hosting environments to determine that a guest is hibernated rather than just powered off, and ensure that they preserve the virtual environment appropriately to allow the guest to resume safely (or bump the hardware_signature in the FACS to trigger a clean reboot instead).
[Fix]
This adds support for it to KVM, and to the guest hibernate code.

[Test Plan]
AWS tested.
[Where problems could occur]
If the final spec of the PSCI v1.3 changes, there may be changes required to this patch series.
