Now that we actually found somebody with that board, properly rework it to provide a CoM/SoM include and a board file for Compulab's SBC-A510. Both the CM-A510 SoM and the SBC-A510 can be configured with different options, so we only enable a minimum set of options. The actual board configuration will have to be set by either the bootloader or user. Although functionally not required, repeat even disabled nodes again to increse their visibility in the dtsi/dts files.
