Subject: [PATCH v2] arm64: dts: qcom: add IPA qcom,qmp property

At least three platforms require the "qcom,qmp" property to be
specified, so the IPA driver can request register retention across
power collapse.  Update DTS files accordingly.

Signed-off-by: Alex Elder <elder@...aro.org>

v2:  Add devicetree@...r.kernel.org to addressee list.

Dave, Jakub, please let Bjorn take this through the Qualcomm tree.
