Subject: [PATCH] imx8mq-kontron-pitx-imx8m: Pass 'u-boot,dm-spl' to console
UART
imx8mq-kontron-pitx-imx8m uses CONFIG_DM_SERIAL=y and CONFIG_DM_SERIAL=y,
so it needs to pass 'u-boot,dm-spl' property to the uart3 and
pinctrl_uart3 nodes so that it can work in SPL.
This fixes the boot on this platform.
