Add full description of USB-MUIC (MAX77693 MUIC) and MUIC-MHL
connections, along with proper USB connector and OTG mode for DWC2 USB
controller.
This fixes dtc W=1 warnings:
Warning (graph_child_address): /i2c-mhl/hdmi-bridge@39/ports: graph node has
single child node 'port@0', #address-cells/#size-cells are not necessary

Changes in v2:
1. Put connector node in the muic node (Henrik)
Not tested on hardware. Please kindly check if peripheral mode is not
broken. Or maybe OTG started to work?
