Research direction
Inspect the definition of struct dwc2_hsotg and the failing dwc_handle_gpwrdn_disc_det function in drivers/usb/dwc2/core_intr.c. Build the kernel with CONFIG_USB_DWC2_PERIPHERAL=y to reproduce the missing-member error; done means the USB Gadget Only configuration compiles successfully.

Description
One of the recent changes to the dwc2 driver has broken USB Gadget Only mode (CONFIG_USB_DWC2_PERIPHERAL=y).
The bus_suspended field of struct dwc2_hsotg is not included in the structure definition if CONFIG_USB_DWC2_PERIPHERAL is defined. This causes a compile error:
drivers/usb/dwc2/core_intr.c: In function 'dwc_handle_gpwrdn_disc_det':
drivers/usb/dwc2/core_intr.c:710:7: error: 'struct dwc2_hsotg' has no member named 'bus_suspended'
