Andreas Sandberg 3e200455bd dev, arm: Add draining to the GIC model 
The GIC model currently adds a delay to interrupts when posting them
to a target CPU. This means that an interrupt signal will be
represented by an event for a short period of time. We currently
ignore this when draining and serialize the tick when the interrupt
will fire. Upon loading the checkpoint, the simulated GIC reschedules
the pending events. This behaviour is undesirable when we implement
support for switching between in-kernel GIC emulation and gem5 GIC
emulation. In that case, the (kernel) GIC model gets a lot simpler if
we don't need to worry about in-flight interrupts from the gem5 GIC.

This changeset adds a draining check to force the GIC into a state
where all interrupts have been delivered prior to checkpointing/CPU
switching. It also removes the now redundant serialization of
interrupt events.
