Suresh Warrier ec13e9b6b1 powerpc/xics: Add icp_native_cause_ipi_rm
Function to cause an IPI by directly updating the MFFR register
in the XICS. The function is meant for real-mode callers since
they cannot use the smp_ops->cause_ipi function which uses an
ioremapped address.

Normal usage is for the the KVM real mode code to set the IPI message
using smp_muxed_ipi_message_pass and then invoke icp_native_cause_ipi_rm
to cause the actual IPI.

The function requires kvm_hstate.xics_phys to have been initialized
with the physical address of XICS.
