dt-bindings: remoteproc: ti: Add mailbox provider nodes to example

In order to make the 'mboxes' property in the TI remoteproc examples
parseable, mailbox provider nodes are needed. Normally, the examples
have a __fixup__ node which can be used for determining each
phandle+arg entry. However, for this binding the arg cells contain a
phandle, and the __fixups__ information can't be used.
