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.
