Sainath Grandhi bf1ff8c98f hv: Offload syncing PIR to vIRR to processor hardware
ACRN syncs PIR to vIRR in the software in cases the Posted
Interrupt notification happens while the pCPU is in root mode.

Sync can be achieved by processor hardware by sending a
posted interrupt notiification vector.

This patch sends a self-IPI, if there are interrupts pending in PIR,
which is serviced by the logical processor at the next
VMEnter
