If CONFIG_PHY is not enabled then the dwc3_setup_phy() returns ENOTSUPP which can be still valid and intentional so modify error check to handle this -ENOTSUPP.

The same error handling exists in drivers/usb/host/xhci-dwc3.c already added by commit d648a50c0a27 ("dwc3: move phy operation to core.c").
