usb: dwc3: Do not get extcon device when usb-role-switch is used
The change breaks device tree based platforms with PHY device and use
usb-role-switch instead of an extcon switch. extcon_find_edev_by_node()
will return EPROBE_DEFER if it can not find a device so probing without
an extcon device will be deferred indefinitely. Fix this by
explicitly checking for usb-role-switch.
At least the out-of-tree USB3 support on Apple silicon based platforms
using dwc3 with tipd USB Type-C and PD controller is affected by this
issue.
