powerpc: introduce the ePAPR embedded hypervisor vmpic driver
The Freescale ePAPR reference hypervisor provides interrupt controller
services via a hypercall interface, instead of emulating the MPIC
controller. This is called the VMPIC.
The ePAPR "virtual interrupt controller" provides interrupt controller
services for external interrupts. External interrupts received by a
partition can come from two sources:
- Hardware interrupts - hardware interrupts come from external
interrupt lines or on-chip I/O devices.
- Virtual interrupts - virtual interrupts are generated by the hypervisor
as part of some hypervisor service or hypervisor-created virtual device.
Both types of interrupts are processed using the same programming model and
same set of hypercalls.
