The dwc3 usb nodes in sm8150.dtsi are currently named differently,
leading to some confusion when one sees the entries in sysfs or
dmesg:
[    1.943482] dwc3 a600000.usb: Adding to iommu group 1
[    2.266127] dwc3 a800000.dwc3: Adding to iommu group 2

Name both the nodes as dwc3@<addr> for consistency.

While at it also arrange the two usb controller, hs-phy and
ss-phy nodes closer in the dts for better readability.

"usb@" is actually the right one, per the rather recent standardization
across the dwc3 bindings.

Ok, yes that makes more sense.
Although a grep for the keyword 'dwc3@', does lead up to quite a few
qcom dts files which use 'dwc3@ 'instead of 'usb@', which seem
inconsistent as per the bindings doc (see [1]).

Maybe I can fix those in v2 as well.

[1]. Documentation/devicetree/bindings/usb/qcom,dwc3.yaml
