usb: add Freescale QE/CPM USB peripheral controller driver
Some of Freescale SoC chips have a QE or CPM co-processor which
supports full speed USB. The driver adds device mode support
of both QE and CPM USB controller to Linux USB gadget. The
driver is tested with MPC8360 and MPC8272, and should work with
other models having QE/CPM given minor tweaks.
