[PATCH v2 2/6] Documentation: devicetree: add bindings to support ARM MHU doorbells

The ARM MHU has mechanism to assert interrupt signals to facilitate inter-processor message based communication. It drives the signal using a 32-bit register, with all 32-bits logically ORed together. It also enables software to set, clear and check the status of each of the bits of this register
