AM43 SoC is in pre-silicon stage, meanwhile it has been modelled in a pre-silicon platform. To validate and boot Linux in pre-silicon platform that emulates an AM43 SoC, add DT build support. As bootloader is not used, bootargs is passed through DT. Note: This would be replaced by an original board support.
