Please make a habit of documenting what changed since the previous

The first cell here should be qcom,sm8150-dwc3. The Linux driver will
"fall through" and match on the less specific "qcom,dwc3", but if we in
the future realize that we have sm8150 specific behavior/quirks we can
make the driver match on the more specific one to implement this.
And similarly the order of the compatibles in &usb_1_hsphy should be
reversed as well.

Bjorn
