Unconditionally setup the IRQ routing on chip reset.
It's safe to call ssb_pcicore_dev_irqvecs_enable() unconditionally, because
it has internal checks for redundant calls.
This fixes problems where hardware will not come up properly
due to quirks in the enable-bit hardware.

I'm not sure if we should push this for 2.6.28.
This fixes quirks when booting from PXE. So only a minority of
the b44 users are affected.
