MLK-20043: arm64: dts: imx8mq-evk: add dual-display support for B3 board 

For imx8mq-evk board, B4 board change touch/mipi-hdmi connected i2c bus
from i2c1 to i2c3. The default dual-display dts file is for the B4
board.
This patch adds a new dts file to also support dual-display on B3 (or
lower) boards.
