This adds support for the Kontron Electronics SoM SL i.MX8MM OSM-S
and the matching baseboard BL i.MX8MM OSM-S.
The SoM hardware complies to the Open Standard Module (OSM) 1.0
specification, size S (https://sget.org/standards/osm).
The existing board configuration for the non-OSM SoM is reused and
allows to detect the SoM variant at runtime.

This adjusts the names of the boards and SoMs to the official naming

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.

The display isn't and won't be used in U-Boot. Also the display setup
is not yet supported in mainline Linux, so even for cases where the
U-Boot devicetree is passed to the kernel there is currently no use
for this configuration.
Selecting the proper configuration in the kernel FIT image automatically
depending on the detected hardware can be handled by a script in the
