MFC r199822:
Drop USB mass storage devices support from ata(4). It is out of the build as
long as I remember, and completely superseded by better maintained umass(4).
It's main idea was to optionally avoid CAM dependency for such devices, but
with move ATA to CAM, it is not actual any more.
No objections: hselasky@, thompsa@, arch@
