dt-bindings: remoteproc: zynqmp-r5: correct dts example

* Correct ZynqMP r5 remoteproc device node example bindings to
remove the old sram, power domain nodes, and add new reserved memory
nodes.
* Fix the remoteproc device node compatible string to match the driver
* Use the mailbox to match the OpenAMP usecase
