USB: add Freescale high-speed USB SOC device controller driver
Freescale high-speed USB SOC can be found on some Freescale processors
among different architectures. It supports both host and device functions.
This driver adds its device support for Linux USB Gadget layer.
It is tested on MPC8349 and MPC8313, but should work on other platforms
with minor tweaks. The driver passed USBCV 1.3 compliance tests. Note
that this driver doesn't yet include OTG support.

Many controller drivers are platform-specific; these
often need board-specific hooks.
