[SCSI] WD33C93: let platform stub override no_sync/fast/dma_mode

Browse Source 
SGI machines with WD33C93 allow usage of burst mode DMA, which increases
performance noticable. To make this selectable by the sgiwd93 stub,
setting the values for no_sync, fast and dma_mode has been moved to the
individual platform stubs.
