ide: remove SATA_*_REG macros
* siimage.c: use hwif->sata_scr[SATA_{ERROR,STATUS}_OFFSET] instead of SATA_{ERROR,STATUS}_REG macros. * Remove no longer needed SATA_*_REG macros. While at it: * Remove needless SATA Status register read from sil_sata_reset_poll(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
