Log:
Doug found that doing a W1C on MCPCIA_INT_REQ just around the time you
clear MCPCIA_INT_MASK0 helps things substantially. So, why not indeed?
Rearrange irq and cookie calculation to use shifts/masks instead
of division. Fix things to correctly remember the intpin for that
one in a million non-INTA PCI device.
