This patch adds a routine to find a usb-conn-gpio in the main DWC3 code.
This will be useful in a subsequent patch where we will reuse the current
extcon VBUS notifier with usb-conn-gpio.

Why not just squash this patch into "[PATCH v5 12/18] usb: dwc3: qcom:
Enable gpio-usb-conn based role-switching" where it is actually used?

IMO its best practice to have smaller patches.

This one adds the routine.
12/18 uses the routine but also

- Triggers a notifer role-switch binding
- Adds an if/else for extcon

Believe it or not I had an internal debate about splitting #12 into two patches !
