ide: move IDE{FLOPPY,TAPE}_WAIT_CMD defines to <linux/ide.h>
While at it: * IDE{FLOPPY,TAPE}_WAIT_CMD -> WAIT_{FLOPPY,TAPE}_CMD * Use enum for WAIT_* defines. There should be no functional changes caused by this patch. Acked-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
