MUSBMHDRC DRD OTG Controller

The MUSBMHDRC DRD OTG Controller (from now on referred to as MUSB is a
Dual-Role OTG IP Core used in several SoC implementations. At the time
of this writing at least OMAP, DaVinci and Blackfins integrate that IP
Core in the SoC and a discrete version of it is supplied by Texas
Instruments as the tusb6010 ASIC.
