Staging: most: add MOST driver's hdm-usb module

This patch adds the hdm-usb module of the MOST driver to the kernel's
driver staging area. This module is part of the MOST driver and handles
the USB interface of the MOST network interface controller.

This patch is needed in order to use the USB peripheral interface of the
network interface controller.
