KVM: arm64: Add AT fast-path support for S1PIE
Emulating AT using AT instructions requires that the live state
matches the translation regime the AT instruction targets.
If targeting the EL1&0 translation regime and that S1PIE is
supported, we also need to restore that state (covering TCR2_EL1,
PIR_EL1, and PIRE0_EL1).
Add the required system register switcheroo.
