[PATCH 1/2] usb: udc: dwc3: Fold board dm_usb_gadget_handle_interrupts() into DWC3 gadget

The dm_usb_gadget_handle_interrupts() has no place in board code. Move
this into DWC3 driver. The OMAP implementation is special, add new weak
dwc3_uboot_interrupt_status() function to decide whether DWC3 interrupt
handling should be called, and override it in OMAP DWC3 code, to repair
the special OMAP interrupt handling code until OMAP gets switched over
to DM UDC proper.
