Enable HS-USB device for the Koelsch board, defining the GPIO that the driver should check when probing (which is the ID output from MAX3355 OTG chip).
Note that there will be pinctrl-related error messages if both internal PCI and HS-USB drivers are enabled but they should be just ignored.

Perhaps I don't understand the pinctrl world yet, but I have a question.
In r8a7791, the USB0_PWEN is GP7_23 and the USB0_OVC is GP7_24. And, the "usb0_pins" is related to these USB0 pins. But, as you know, the koelsch has a OTG ID pin and it connects to GP5_31 via MAX3355 chip.
The GPIO pins are not requested via pinctrl.
So, would you tell me why koelsch needs the pinctrl?
Because at least USB0_OVC/VBUS is used by HS-USB. I decided not to modify the R8A7791 PFC driver in order to create a group consisting of that signal alone (like on R8A7790), because we don't need to read GP7_23 on these boards, unlike Lager.
