sata_sil24: don't use NCQ if marvell 4140 PMP is attached
When 4140 PMP is attached to sil24, NCQ commands to fan out port 1 and
2 (0 based) often stall if commands are in progress to other ports.
I've tried a number of things but can't tell what's going on. It
never happens w/ ahci and reportedly sata_mv which can issue NCQ
commands to multiple devices simultaneously like sil24 does.
Disable NCQ for devices behind 4140 PMP for the time being.
