[PATCH v2 13/19] imx: kontron-sl-mx8mm: Prepare for other i.MX8MM SoM types

[Frieder Schrempf]

From: Frieder Schrempf <frieder.schrempf at kontron.de>

This sets an env variable 'som_type' from the board code. It can
later be used by environment scripts, e. g. to select the proper
devicetree for the board.
