Remove stale ide.h "configuration options": * INITIAL_MULT_COUNT - always defined to 0 * SUPPORT_SLOW_DATA_PORTS - unused * OK_TO_RESET_CONTROLLER - always defined to 1 * DISABLE_IRQ_NOSYNC - always defined to 0 Leave SUPPORT_VLB_SYNC (defined to 0 for CRIS and FRV, otherwise to 1) for now but disallow overriding it by <asm/ide.h>. There should be no functionality changes caused by this patch. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
