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.
