It would appear that all of the selftests are using the same exact
layout for the GIC frames. Fold this back into the library
implementation to avoid defining magic values all over the selftests.
This is an extension of Colton's change, ripping out parameterization of
from the library internals in addition to the public interfaces.

Add basic support for ARM Generic Interrupt Controller v3.
The support provides guests to setup interrupts.
The work is inspired from kvm-unit-tests and the kernel's
GIC driver (drivers/irqchip/irq-gic-v3.c).
