It's generally useful. On other architectures the UDC capable hardware might
not be very common, but the dummy HCD makes it possible to use such hardware
for development and emulation of USB gadget driver code.

Changes since v2:
* Rebased on v3.14-rc4-45-gd2a0476 (fedora package git: 2323b0271)
* Do not move the modules to modules-extra
According to Peter & Adam, even certain Intel hardware has device mode
capability, so this certainly is useful.
