KVM: arm64: Use read-only helper for reading VM ID registers

Browse source

IDREG() expands to the storage of a particular ID reg, which can be
useful for handling both reads and writes. However, outside of a select
few situations, the ID registers should be considered read only.

Replace current readers with a new macro that expands to the value of
the field rather than the field itself.
