[PATCH v2 1/4] dt-bindings: sram: Document qcom,rpm-msg-ram

[Bjorn Andersson <bjorn.andersson@linaro.org>]

The Qualcomm SMEM binding always depended on a reference to a SRAM node
of compatible "qcom,rpm-msg-ram", document this as part of the SRAM
binding.

The SRAM is consumed as a whole and not split up using subnodes, so
properties related to this are not required.

Changes since v1:
- New patch, to resolve issue with the existing qcom,smem example
