[PATCH] usb: dwc3-generic: Fix build errors when USB_DWC3_GADGET is disabled

[Jonas Karlman]

Build fail with the following error when DM_USB_GADGET is enabled and
USB_DWC3_GADGET is disabled:

  dwc3/dwc3-generic.o: in function `dm_usb_gadget_handle_interrupts':
  dwc3/dwc3-generic.c:201:(.text.dm_usb_gadget_handle_interrupts+0x10):
    undefined reference to `dwc3_gadget_uboot_handle_interrupt'

Build also fail with the following error when USB_GADGET_DWC2_OTG +
DM_USB_GADGET is enabled and USB_DWC3_GADGET is disabled:

  gadget/dwc2_udc_otg.o: in function `dm_usb_gadget_handle_interrupts':
  gadget/dwc2_udc_otg.c:947: multiple definition of `dm_usb_gadget_handle_interrupts';
    dwc3/dwc3-generic.o:dwc3/dwc3-generic.c:197: first defined here

Fix this by checking for USB_DWC3_GADGET in addition to DM_USB_GADGET.
