ide: remove ->mmio flag from ide_hwif_t
Since scc_pata host driver no longer uses IDE PCI layer / ide_dma_setup() and all other ->mmio users set also IDE_HFLAG_MMIO host flag we can safely remove ->mmio flag. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
