hi,

bits in the features supported/enabled register,
defined in sys/dev/ata/atareg.h, are named like:
	WDC_CMD2_DM
	ATA_CMD2_RWQ
	WDC_CAP_LBA48
	WDC_CAP_QUEUE
(note that ATA_CMD2_RWQ and WDC_CAP_QUEUE are for
the same bit, "READ/WRITE DMA QUEUED supported".)

they seem very inconsisitent to me.
i'd like to add definitions for some new bits
but i'm not sure which prefix i should use.
WDC_CMD2_, WDC_CAP_, ATA_CMD2_, or something else?

any ideas?  is it ok to rename them to have the same prefix?
