A new function, psci_system_off(), is added which implements the PSCI
SYSTEM_OFF function. A call causes the hypervisor to terminate the virtual
machine.
We take this opportunity to rename psci_sys_reset() to psci_system_reset()
to match the name of the PSCI function SYSTEM_RESET that it implements.
Consumers for the function will be added in a later patch.
