Samsung micro-USB 11-pin connector

Samsung micro-USB 11-pin connector is an extension of micro-USB connector.
It is present in multiple Samsung mobile devices.
It has additional pins to route MHL traffic simultanously with USB.

The bindings are superset of usb-connector bindings for micro-USB connector[1].

Required properties:
- compatible: must be: "samsung,usb-connector-11pin", "usb-b-connector",
- type: must be "micro".

Required nodes:
- any data bus to the connector should be modeled using the OF graph bindings
  specified in bindings/graph.txt, unless the bus is between parent node and
  the connector. Since single connector can have multpile data buses every bus
  has assigned OF graph port number as follows:
    0: High Speed (HS),
    3: Mobile High-Definition Link (MHL), specific to 11-pin Samsung micro-USB.
