Subject: [PATCH 03/10] arm64: dts: qcom: Add a device tree for PMK8350 on SID6

PMK8350 is shipped on SID6 with some SoCs, for example with SM6375.
Add a DT with the SID changed to allow it to work.

Unfortunately, the entire DT needs to be copied even if the diff is
very little, as the node names are not unique. Including pm6125 and
pmk8350 together for example, would make pmk8350 overwrite the pm6125
node, as both are defined as 'pmic@0'.
