Revert "Merge branch 'qcom-dts-updates'"

This reverts commit b79c6fba6c, reversing
these changes made to 0ac26271344478ff718329fa9d4ef81d4bcbc43b:

  commit 6a0eb6c9d9 ("dt-bindings: net: qcom,ipa: make imem interconnect
                       optional")
  commit f8bd3c82bf ("arm64: dts: qcom: sc7280: add IPA information")
  commit fd0f72c34b ("arm64: dts: qcom: sc7180: define ipa_fw_mem node")

I intend for these commits to go through the Qualcomm repository, to
avoid conflicting with other activity being merged there.
