Does it make sense to make these changes in snps,dwmac.yaml since you're
trying to do this generically for stmmac? I don't poke bindings super
often so might be a silly question, the inheritance of snps,dwmac.yaml
into the various platform specific bindings (qcom,ethqos.yaml) would
then let you define it once in the snps,dwmac.yaml right?

Sorry to bikeshed, and with Krzysztof's review on this already its
probably unnecessary, but would names like cpu-mac and mac-mem be
more generic / appropriate? I see that sort of convention a lot in the
other bindings, and to me those read really well and are understandable.
