FROMLIST: arm64: dts: qcom: lemans-evk: enable UART0 for robot board

The lemans-evk mezzanine connector supports a robot expansion board that
requires UART0, which is currently disabled. This prevents the expansion
board from exchanging data and control commands.

Enable UART0 and assign the serial2 alias to provide stable device
enumeration for the expansion board.
