KVM: arm64: Add RMW specific sysreg accessor

Browse source 
In a number of cases, we perform a Read-Modify-Write operation on
a system register, meaning that we would apply the RESx masks twice.

Instead, provide a new accessor that performs this RMW operation,
allowing the masks to be applied exactly once per operation.
