currently libata-sff is completely ignoring the enabled/disabled status

touch a non responding memory area (i.e. a disabled interface) you crash
the box.

Fix by checking the CNTRL bits to see if the port is enabled before
trying to poke it.

Ping on this.

Since 1/2 is an essential fix to prevent a boot panic on parisc, I can
just take them through the parisc tree.
