[PATCH 1/2] dt-bindings: arm: add MBa93xxCA as mainboard for TQMa91xxCA and TQMa91xxLA SOM

[Alexander Stein]

From: Markus Niebel <Markus.Niebel at ew.tq-group.com>

TQMa93xxLA and TQMa93xxCA are two series of feature compatible SOM
using NXP i.MX91 SOC in 11x11 mm package.

MBa93xxCA is a starterkit base board usable for TQMa91xxCA and TQMa91xxLA
soldered on an adapter board to demonstrate use cases without display but
more interfaces.
