b44: Unconditionally enable interrupt routing on reset
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.
