Still not specific. Put the SoC name(s) in it.

'micro' is certainly not right for USB-C. Probably should be omitted?

Per Rob's request make this:
Should contain "qcom,qcs404-snps-usb-ssphy" and "qcom,snps-usb-ssphy"
You can then leave the driver matching on qcom,snps-usb-ssphy for now
and if we ever find this to be incompatible with other platforms we can
make the driver match on the platform-specific compatible.

The USB-C connector is attached both to the HS and SS PHYs, so I think
you should represent this external to this node and use of_graph to
query it.
So the connector should look similar to example 2 in
connector/usb-connector.txt.
