[PATCH 0/2] KVM: arm64: Minor improvements to RAZ register handling

[Alexandru Elisei]

What sparked these two small patches is the series that fixed the PMU reset
values and their visibility from userspace, more specifically the
discussion around the patch that removed the PMSWINC_EL0 shadow register
[1].

The patches are straightforward cleanups without any changes in
functionality.

Tested on a rockpro64, by running kvm-unit-tests under qemu.

  KVM: arm64: Return early from read_id_reg() if register is RAZ
