[Zion][Denali] Move to MSI for AHCI devices.

Browse source 
This will allow us to properly do interrupts for XHCI devices in the
future.

Also move PCI device header parsing to a shared library.

Get rid of the old irq register format which supplied an irq number and
instead pass the appropriate irq number back out to the caller.
