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.

The code for this feature was included in the v5.17 cycle, but the
DTS file updates were not accepted until v5.18-rc1.
