KVM: arm64: Add support for PSCI v1.2 and v1.3
As with PSCI v1.1 in commit 512865d83fd9 ("KVM: arm64: Bump guest PSCI
version to 1.1"), expose v1.3 to the guest by default. The SYSTEM_OFF2
call which is exposed by doing so is compatible for userspace because
it's just a new flag in the event that KVM raises, in precisely the same
way that SYSTEM_RESET2 was compatible when v1.1 was enabled by default.
