rambi: distribute IRQs away from PIRQA on pci devices 

Some of the drivers in the kernel were not so happy about
having shared IRQs. Also, sharing IRQs means more code
needs to be run in interrupt context to determine if the IRQ
was meant for a particular device. Fix this.

No more 'mmc1: got irq while runtime suspended' messages.

BUG=chrome-os-partner:24056
BRANCH=None
TEST=Built and booted. Looked at /proc/interrupts and noted no
     more sharing between pci devices.
