Currently platform specific PCI device IRQ assignment is run during
the boot code, this results in a wide array of differing code paths
and causes hot-plugged PCI devices to not be assigned IRQs, this
patch removes the boot time initialisation of such IRQs and instead
registers assignment functions to be run during the PCI device enable
path.
