dt-bindings: remoteproc: imx_rproc: Document memory-region-names to avoid implicit ABI

Document the optional memory-region-names property.
 
The driver currently derives the memory region type from the referenced
memory node name, creating a implicit DT ABI. Since memory node names are
not constrained by the binding, incorrect names can silently pass DT
validation, as seen in examples using "vdevbuffer" instead of
"vdev0buffer" ([1] and [2]).

Add memory-region-names to explicitly identify the expected memory regions
and avoid relying on memory node names as ABI.
