Warner Losh bbc84740c1 Latest round of usb cleanups:
o Consistently use device_foo_t and bus_foo_t for functions implementing
  device_foo and bus_foo respectively.  Adjust those routines that were wrong
  (we should do this throughout the tree).
o make all the modules depend on usb.  Otherwise these modules won't
  load.
o ucycom doesn't need usb_port.h
o Minor unifdefing
o uhub, umass, ums, urio, uscanner conversion complete.
o ukbd: Remove the NO_SET_PROTO quirk (fixes a PR 77940).  NetBSD removed
  their check and setting the proto a long time ago.
o umodem panic fixed.  UQ_ASSUME_CM_OVER_DATA quirk removed because I've never
  seen a umodem that needed this rejection for proection (this gets rid of
  ~20% of the quirks).
