ata_piix: verify SIDPR access before enabling it
On certain configurations (certain macbooks), even though all the
conditions for SIDPR access described in the datasheet are met,
actually reading those registers just returns 0 and have no effect on
write. Verify SIDPR is actually working before enabling it.
This is reported by Ryan Roth in bz#10512.
