MLK-23241 imx8dx_mek: Add iMX8DX MEK board support

iMX8DX MEK board has similar design with 8QXP MEK. The major changes are
1. DDR changed to 16bits 1GB DDR part
2. USB3.0 is removed and only support OTG on typec port. (No SW change needed)

This patch adds new defconfigs and DTS file for this new board.
