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

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.

Enable this feature, now that 8ff8bdb8c92d6 ("net: ipa: request IPA
register values be retained") has been accepted into linux-5.15.y.
