Avi Kivity 22ec3283ef irq: introduce qemu_irq_proxy()
In some cases we have a circular dependency involving irqs - the irq
controller depends on a bus, which in turn depends on the irq controller.
Add qemu_irq_proxy() which acts as a passthrough, except that the target
irq may be set later on.

Peter Maydell 9793212bb0 hw/irq: Add qemu_irq_split() so one GPIO output can feed two inputs
Add a qemu_irq_split() function which allows a board to wire a single
GPIO output up to two GPIO inputs. This is needed for realview boards,
where the MMC card status is visible both in a system register and
via a PL061 GPIO module.
