sata_mv: fix pmp drives not found
Part three of simplifying/fixing handling of the main_irq_mask register
to resolve unexpected interrupt issues observed in 2.6.26-rc*.
Partially fix a reported bug whereby we sometimes miss seeing drives on
a port-multiplier, as reported by Gwendal Grignou <gwendal@google.com>.
The problem was that we were receiving unexpected interrupts
during EH from POLLed commands while accessing port-multiplier registers.
These unexpected interrupts can be prevented by masking the DONE_IRQ bit
for the port whenever not operating in EDMA mode.
Also fix port_stop() to mask all port interrupts.
