I'm not at all sold on this to be honest.  Coverity just picked up a
bunch of issues in this subsystem during the last merge window and the
overall USB subsystem maintainer doesn't even enable these drivers in
his build testing.  It seems to be a lot of churn for very little
gain.

Also, if the dummy HCD driver is the only marginally useful thing on
x86, why copy all of the stuff in the ARM config blindly?  Isn't it
feasible to enable GADGET and HCD on x86 and leave everything else
off?
