The select_dr_mode operation is executed when the glue driver is probed.
The role of this optional function is to configure the operating mode
of the controller at the glue level.

446e3a205b dwc3-generic: Handle the PHYs, the clocks and the reset lines
This make the driver more generic. At this point this driver can replace
the dwc3-of-simple implementation.
Make the description in the Kconfig more generic too.

0131162439 dm: usb: create a new UCLASS ID for USB gadget devices
UCLASS_USB_DEV_GENERIC was meant for USB devices connected to host
controllers, not gadget devices.
Adding a new UCLASS for gadget devices alone.

Also move the generic DM code for USB gadgets in a separate file for
clarity.

ff8d755834 usb: udc: implement DM versions of usb_gadget_initialize()/_release()/_handle_interrupt()
When DM_USB_GADGET the platform code for the USB device must be replaced by
calls to a USB device driver.

usb_gadget_initialize() probes the USB device driver.
usb_gadget_release() removes the USB device driver.

49d674547c usb: dwc3: Add generic DWC3 glue logic driver
By enabling BLK by default this is the next driver which needs to get
support for DM_USB. Adding generic DWC3 glue logic which only
parse nodes and read device mode. Based on it probe proper
host/peripheral DWC3 drivers for it.
