Commit 65dc2e725286 ("usb: dwc2: Update Core Reset programming flow.") revealed that the phy isn't ready immediately after enabling it's clocks. The dwc2_check_core_version() fails and the dwc2 usb driver errors out.
Add a short delay to let the phy get up and running. There isn't any documentation how much time is required, the value was chosen based on tests.
Applied, thanks
