Rob Herring b32dcf23a0 dt-bindings: Drop kernel copy of common reserved-memory bindings
The common reserved-memory bindings have recently been copied from the
kernel tree into dtschema. The preference is to host common, stable
bindings in dtschema. As reserved-memory is documented in the DT Spec,
it meets the criteria.

The v2023.09 version of dtschema is what contains the reserved-memory
schemas we depend on, so bump the minimum version to that. Otherwise,
references to these schemas will generate errors.

description: |
This document defines the bindings for the remoteproc component that loads and
boots firmwares on the Renesas R-Car family chipset.
R-Car gen3 family may have a realtime processor, this processor shares peripheral
and RAM with the host processor with the same address map.

List of phandles to the reserved memory regions associated with the
remoteproc device. This is variable and describes the memories shared with
the remote processor (e.g. remoteproc firmware and carveouts, rpmsg
vrings, ...).
