From: Matthew Minter <matt@xxxxxxxxxxxx>
PCI IRQs are currently configured to be enabled once at boot in a
dedicated pass. This means that PCI devices which are hot-plugged after
boot time will not be given an IRQ, this patch-set fixes this by
registering the assignment function to be called later in the device
enable path.
