KVM: arm64: Factor out core register ID enumeration
In preparation for adding logic to filter out some KVM_REG_ARM_CORE registers from the KVM_GET_REG_LIST output, this patch factors out the core register enumeration into a separate function and rebuilds num_core_regs() on top of it. This may be a little more expensive (depending on how good a job the compiler does of specialising the code), but KVM_GET_REG_LIST is not a hot path. This will make it easier to consolidate ID filtering code in one place. No functional change.
