Subject: [PATCH net-next v3 1/1] dt-bindings: net: qcom,ipa: make imem interconnect optional

On some newer SoCs, the interconnect between IPA and SoC internal
memory (imem) is not used. Update the binding to indicate that
having just the memory and config interconnects is another allowed
configuration.

v3: Based on net-next/master; sending for inclusion there.
v2: Based on linux-next/master, to be taken via Qualcomm repository.

I sent version 2 of this only to linux-arm-msm, but Bjorn reminded
me this binding update ought to go through the net-next repository.
