[PATCH v1 3/3] ARM: dts: imx7d: add Variscite MX7CustomBoard support

From: Stefano Radaelli <[email protected]>

Add device tree support for the Variscite MX7CustomBoard carrier
board with the VAR-SOM-MX7 system on module.

Add the supported board configurations for both VAR-SOM-MX7 hardware
revisions, including eMMC, NAND and WM8731 variants.

Also add the resulting DTBs to the i.MX7D device tree Makefile.
