Modified Files:
	src/sys/dev/ata: ata_wdc.c wd.c

Log Message:
Do not force ATA_SINGLE on devices that don't support READ/WRITE MULTI.  We
just have to take an interrupt for each sector.
Tested with one laptop disk (which normally runs in DMA mode and was forced
to single-sector transfers) and 3 CF cards.  Increases the performance of
the CF cards substantially (760KB/s->1240KB/s in one case, 410KB/s->750KB/s
in the other two cases).
