Subject: [PATCH 1/3] dt: bindings: add bindings for TQMa93xxLA SOM

From: Markus Niebel <Markus.Niebel@...tq-group.com>

TQMa93xxLA is a SOM variant in the TQ-Systems GmbH TQMa93xx series using
NXP i.MX93 CPU on an LGA type board.
MBa93xxCA is a starterkit base board for TQMa93xxLA on an adapter board.

+          All SOM and CPU variants use the same device tree hence only one
+          compatible is needed. Bootloader disables all features not present
+          in the assembled SOC.
