[PATCH v2 5/7] dt-bindings: watchdog: add SMARC-sAM67 support

[Michael Walle]

The SMARC-sAM67 board has an on-board uC which has the same register
interface as the older CPLD implementation on the SMARC-sAL28 board.
Although the MCU emulates the same behavior, be prepared for any quirks
and add a board specific compatible.
