Subject: [PATCH v4 3/3] arm64: dts: qcom: sm6350: Use specific qmpphy
 compatible

The sc7180 phy compatible works fine for some cases, but it turns out
sm6350 does need proper phy configuration in the driver, so use the
newly added sm6350 compatible.

Because the sm6350 compatible is using the new binding, we need to
change the node quite a bit to match it.

This fixes qmpphy init when no USB cable is plugged in during bootloader
stage.
