ARM: dts: samsung: exynos4412-midas: add USB connector and USB OTG

Browse source 
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
