arm64: dts: ti: iot2050: Support IOT2050-SM variant

Browse source 
Main differences between the new variant and Advanced PG2:

1. Arduino interface is removed. Instead, an new ASIC is added for
   communicating with PLC 1200 signal modules.
2. USB 3.0 type A connector is removed, only USB 2.0 type A connector is
   available.
3. DP interface is removed. Instead, to communicate with PLC 1200 signal
   modules, a USB 3.0 type B connector is added but the signals are
   actually not USB.
4. DDR size is increased to 4 GB.
5. Two sensors are added, one tilt sensor and one light sensor.

The light sensor it not yet added to the DT at this stage as it depends
on to-be-added bindings.
