KVM: arm64: Allow userspace to change ID_AA64ISAR{0-2}_EL1
Almost all of the features described by the ISA registers have no KVM
involvement. Allow userspace to change the value of these registers with
a couple exceptions:
- MOPS is not writable as KVM does not currently virtualize FEAT_MOPS.
- The PAuth fields are not writable as KVM requires both address and
generic authentication be enabled.
