ide: add IDE_HFLAG_NO_{IO32_BIT,UNMASK_IRQS} host flags
* Use the same bit for IDE_HFLAG_CS5520 and IDE_HFLAG_VDMA host flags (both are used only by cs5520 host driver currently). * Add IDE_HFLAG_NO_IO32_BIT host flag and use it instead of ->no_io_32bit ide_hwif_t field. * Add IDE_HFLAG_NO_UNMASK_IRQS host flag, then convert dtc2278 and rz1000 host drivers to use it. There should be no functionality changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
