usb: dwc3: gadget: add common endpoint configuration for dwc3 udc driver

This patch adds code to select standard, commonly used usb endpoint
configuration (ep1in-bulk, ep2out-bulk, ep3in-int) to dwc3 driver. This
ensures compatibility with old userspace and windows drivers, which
expects hardcoded endpoint numbers.
