Hmmm... EH, NCQ, PM stuff doesn't really interfere with irq-pio.  The
only thing which needs special attention is hotplug support for
sata_sil as the driver requires PIO HSM implementation but needs to
use its own interrupt handler.  So, we need to separate out PIO HSM
from ata_host_intr() and allow LLDD irq handlers to drive it.

Albert, what do you think?
