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.
