ide: remove dead Virtual DMA support
Lets remove dead Virtual DMA support for now so it doesn't clutter core IDE code (it can be bring back when there is a need for it): * Remove IDE_HFLAG_VDMA host flag. * Remove ide_drive_t.vdma flag. * cs5520.c: remove stale FIXMEs, cs5520_dma_host_set() and cs5520_dma_ops (also there is no longer a need to set IDE_HFLAG_NO_ATAPI_DMA). There should be no functional changes caused by this patch. Cc: TAKADA Yoshihito <takada@mbf.nifty.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
