MPIDR is used to show multiprocessor affinity on arm platform. It is
also used to provide an additional processor identification mechanism
for scheduling purposes. To add support for setting MPIDR from usersapce
an vcpu ioctl KVM_CAP_ARM_MP_AFFINITY is introduced. This patch series is
needed to help qemu to build the accurate cpu topology for arm.

Add KVM_CAP_ARM_MP_AFFINITY extension for userspace to check
whether KVM supports setting MPIDR on AArch64 platform. Thus
we can give userspace control over the MPIDR to present
cpu topology information.
