dt-bindings: net: qcom,ipa: add optional qcom,qmp property
For some systems, the IPA driver must make a request to ensure that
its registers are retained across power collapse of the IPA hardware.
On such systems, we'll use the existence of the "qcom,qmp" property
as a signal that this request is required.
