KVM: arm64: re-factor hyp.S debug register code
This is a pre-cursor to sharing the code with the guest debug support. This replaces the big macro that fishes data out of a fixed location with a more general helper macro to restore a set of debug registers. It uses macro substitution so it can be re-used for debug control and value registers. It does however rely on the debug registers being 64 bit aligned (as they happen to be in the hyp ABI).
