KVM: arm64: Extract MPIDR computation into a shared header

Browse source

Extract the vCPU MPIDR computation embedded in reset_mpidr() into a
kvm_calculate_mpidr() inline in sys_regs.h, so it can be computed
without duplicating the logic. A follow-up series reuses it to reset
protected vCPUs at EL2.

No functional change intended.
