Log Message:

arm-common: Prefix GIC functions with their target version

Now that we link both GIC implementations into the same binary, this
prefixing helps telling the origin of symbols apart.

No functional changes.

Log Message:
-----------
core: Add barrier to shutdown procedure

Add a barrier that waits for all CPUs to enter the disable hypercall
prior to performing any shutdown step. This avoids races in case some
CPU rushes forward with disabling common hypervisor support while
another is still operational, possibly triggering code paths that
expects Jailhouse to be still working.

One such scenario can be triggered on ARM once we start migrating
pending interrupts from the hypervisor queue back to the physical
irqchip.

arm-common: Let cpu_shutdown return an error if the GIC is uninitialized

This allows the caller to decide if further deinitializations are
required.

Log Message:

arm-common: Migrate pending interrupts on shutdown

When we have interrupts pending for virtual injection, we need to
migrate them into the physical queue prior to disabling Jailhouse.
Failing to do so means loosing interrupts, most often the timer IRQ.
This error could be triggered by running jailhouse enable/disable in a
tight loop.
