[Stefano Radaelli <stefano.radaelli21@gmail.com>]

From: Stefano Radaelli <stefano.r@variscite.com>

Add DT compatible strings for the Variscite VAR-SOM-MX7 SoM variants

Both the first and second hardware revisions are supported, including
eMMC and NAND configurations, with WM8731 variants available for the
first hardware revision.
