The Linux support for dwc3 on Apple silicon SoCs switched to using a
apple specific glue driver [1] that uses it own compatible string. The
glue driver handles platform specific requirements on the interaction
between dwc3 and the USB2/USB3 PHY and reset-controller for USB role
switches and plug events.
To keep USB working as before when the nodes still carried "snps,dwc3"
as compatible add "apple,t8103-dwc3" to the of match table. Eventually
it is probably advisable to add a dwc3-apple glue driver and write code
for the currently empty Apple Type-C PHY driver in phy-apple-atc.c.
