currently libata-sff is completely ignoring the enabled/disabled status
of the interfaces.  This is a real problem on parisc because if you
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.

It's in libata-dev.git#upstream and #NEXT (linux-next) at present.
