ide: pass command to ide_map_sg()
* Set IDE_TFLAG_WRITE flag and ->rq also for ATA_CMD_PACKET
commands.
* Pass command to ->dma_setup method and update all its
implementations accordingly.
* Pass command instead of request to ide_build_sglist(),
*_build_dmatable() and ide_map_sg().
While at it:
* Fix scc_dma_setup() documentation + use ATA_DMA_WR define.
* Rename sgiioc4_build_dma_table() to sgiioc4_build_dmatable(),
change return value type to 'int' and drop unused 'ddir'
argument.
* Do some minor cleanups in [tx4939]ide_dma_setup().
There should be no functional changes caused by this patch.
