ide-pmac: add ->cable_detect method
Add ->cable_detect method and remove no longer needed pmif->cable_80 flag (there is also no need to mask ->udma_mask now). This fixes: - forced ignoring of cable detection (needed for some CF devices & debug) - cable detection for warm-plug Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
