dt-bindings: soc: ti,omap-dmm: Convert to DT schema
Convert the TI OMAP Dynamic Memory Manager (DMM) dt binding
from text format to DT schema.
During conversion following changes were made:
- Move file from /bindings/arm/omap to /bindings/soc/ti/
- Make the 'ti,hwmods' property optional and mark it deprecated as it is
no longer used, it is kept to support legacy dtbs.
- Add the missing required property 'interrupts' to example node.
