ide: add ->read_status method
* Remove ide_read_status() inline helper. * Add ->read_status method for reading ATA Status register and use it instead of ->INB. While at it: * Don't use HWGROUP() macro. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
