PATCH 1/1 staging: mt7621-pci: Hack 2 more PCI interrupts for gnubee1

The mt7621-pci support 3 pci devices and has 3 interrupts. Each of these need to be enabled by the same sort of hack to map hwirq number to virq number.
This is a hack which will go as soon as I understand how this is supposed to work.
