[PATCH v6 3/3] arm64: dts: freescale: Add minimal dts support for imx943 evk

[Jacky Bai <ping.bai@nxp.com>]

Add the minimal board dts support for i.MX943 EVK. Only the console uart,
SD & eMMC are enabled for linux basic boot.

 - v6 changes:
  - reorder the build entry in Makefile alphabetically
  - remove unused sleep pinctrl for usdhc node
  - add no-mmc, no-sdio properties for usdhc2 as it is used for SD card

 - v5 changes:
  - remove the unused and not documented 'fsl,cd-gpio-wakeup-disable'
    property from usdhc node.

 - v4 changes:
  - no

 - v3 changes:
  - no

 - v2 changes:
  - newly added for board dts
