KVM: arm64: Handle all ID registers trapped for a protected VM
A protected VM accessing ID_AA64ISAR2_EL1 gets punished with an UNDEF,
while it really should only get a zero back if the register is not
handled by the hypervisor emulation (as mandated by the architecture).
Introduce all the missing ID registers (including the unallocated ones),
and have them to return 0.
