Mark Lord a3718c1f23 sata_mv: tidy host controller interrupt handling 
Tidy up host controller interrupt handling, by moving the weirdo
bit shifting from mv_interrupt() to mv_host_intr().

This lets us take advantage of the MV_PORT_TO_SHIFT_AND_HARDPORT() macro
from an earlier patch to greatly simplify the port numbering logic.

Also, defer reading the hc_irq_cause (one per hc) until it is
actually proven to be needed.  This may save a microsecond or
so per interrupt, on average (a later patchset will further reduce
unnecessary register reads throughout the driver).

Apart from that, we still leave the actual IRQ handling logic alone.
Subsequent patches in this series will address that.
