This patch implements libata.force module parameter which can
selectively override ATA port, link and device configurations
including cable type, SATA PHY SPD limit, transfer mode and NCQ.
For example, you can say "use 1.5Gbps for all fan-out ports attached
to the second port but allow 3.0Gbps for the PMP device itself, oh,
the device attached to the third fan-out port chokes on NCQ and
shouldn't go over UDMA4" by the following.
libata.force=2:1.5g,2.15:3.0g,2.03:noncq,udma4

Okay, the build failure is dependent on compiler version. 4.1.2 fails
but 4.2.1 is okay. I was using 4.2.1 so I didn't know about it.
const is dropped from the offending structure and comment is added.
