Subject: [PATCH 5.15 124/124] arm64: dts: qcom: add IPA qcom,qmp property

From: Alex Elder <elder@...aro.org>

commit 73419e4d2fd1b838fcb1df6a978d67b3ae1c5c01 upstream.

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.
