ide-pmac: use __ide_wait_stat()
* Use __ide_wait_stat() instead of wait_for_ready() in pmac_ide_do_setfeature(). While at it do following changes to match __ide_wait_stat() call in ide_config_drive_speed(): * Wait WAIT_CMD time (20 sec) instead of 2 sec for device to clear BUSY_STAT. * Check DRQ_STAT bit (shouldn't be set for good device status). Also remove no longer needed wait_for_ready() from ide-iops.c. Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
