KVM: arm64: Handle PSCI for protected VMs

Add PSCI 1.0 support for protected VMs. All mandatory functions
are supported, except for SYSTEM_RESET, because pKVM doesn't have
a way of resetting protected VMs yet.

Some VMMs issue a SYSTEM_RESET when tearing down a VM, therefore,
for now, we repaint SYSTEM_RESET calls as SYSTEM_OFF.
