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. Reflect this in the binding by moving the definition of the "imem" interconnect to the end and defining minItems to be 2 for both the interconnects and interconnect-names properties.
