Staging: most: add MOST driver's hdm-dim2 module 



This patch adds the hdm-dim2 module of the MOST driver to the kernel's
driver staging area. This module is part of the MOST driver and handles
the MediaLB interface of the MOST network interface controller.

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

	---help---

	  Say Y here if you want to connect via MediaLB to network tranceiver.

	  This device driver is platform dependent and needs an addtional

	  platform driver to be installed. For more information contact

	  maintainer of this driver.



	  To compile this driver as a module, choose M here: the

	  module will be called hdm_dim2.
