[PATCH v1 2/7] dt-bindings: mfd: sl28cpld: add sa67mcu compatible

[Michael Walle]

The Kontron SMARC-sAM67 module features an on-board house keeping uC.
It's designed to be compatible with the older on-board CPLD used on the
SMARC-sAL28 board. To be prepared for any board specific quirks, add a
specific compatible.
