Add support for running the driver inside a guest/VM under a hypervisor.

The main difference include:
1. supporting introducing notification pending interrupt and
2. Avoiding creation of all the notification bitmaps as they must be
   created by the hypervisor before the VM is initialised

The guest may need to use a notification pending interrupt instead of
the schedule receiver interrupt.
