dts: bindings: Add memory-region property in bindings Since the introduction of the `zephyr,memory-region` compatible to create new memory region, drivers can now use the newly defined region in the DT by using the macro LINKER_DT_NODE_REGION_NAME() on the node_id to retrieve the region name and possibly allocated data or variables in that region (or for whatever other use). This is assuming though that the driver knows in advance the node_id to reference. A better approach is to add a new generic 'memory-region' property that can be used by any driver to reference a region by using a phandle, so that the driver can use that to retrieve the memory-region of interest.
