Subject: [PATCH 1/2] dt-bindings: reset: imx-src: add syscon and simple-mfd
 compatibles

This allows passing the reboot mode from the OS to the bootloader via the
syscon-reboot-mode binding. Add a "simple-mfd" to support probing such a
child node. The actual reboot mode node could then be defined in a
board device-tree or fixed up by the bootloader.
