<div class='commit-subject'>irqchip/mips-gic: Implement activate op for device domain</div><div class='commit-msg'>If an IRQ is setup using __setup_irq(), which is used by the
request_irq() family of functions, and we are using an SMP kernel then
the affinity of the IRQ will be set via setup_affinity() immediately
after the IRQ is enabled. This call to gic_set_affinity() will lead to
the interrupt being mapped to a VPE. However there are other ways to use
IRQs which don't cause affinity to be set, for example if it is used to
chain to another IRQ controller with irq_set_chained_handler_and_data().
The irq_set_chained_handler_and_data() code path will enable the IRQ,
but will not trigger a call to gic_set_affinity() and in this case
nothing will map the interrupt to a VPE, meaning that the interrupt is
never received.

Fix this by implementing the activate operation for the GIC device IRQ
domain, using gic_shared_irq_domain_map() to map the interrupt to the
correct pin of cpu 0.
