arm: dts: iot2050: Add support for M.2 variant
Add support for the M.2 board based on the iot2050 advanced board.
The board has two m.2 connectors, one is B-keyed, the other E-keyed.
The B-key slot can connect 5G/SSD devices, and E-key can be used for
WIFI/BT devices.
This variant is covered by PG2 firmware image.
