ahcisata(4): disable NCQ for VIA VT8251 integrated SATA controller.

NCQ support is known to be non-compliant or broken on this chipset,
causing timeouts and instability.

The issue is reproducible in NetBSD using 'smartctl -a`.

The workaround is to disable NCQ, which has already been done in other
OS drivers.
