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.
