usb: dwc2-otg: make regs_otg (in platdata) a uintptr_t

The regs_otg field in uintptr_t of the platform data structure for
dwc2-otg has thus far been an unsigned int, but will eventually be
casted into a void*.

This raises the following error with GCC 6.3 and buildman:
  ../drivers/usb/gadget/dwc2_udc_otg.c: In function 'dwc2_udc_probe':
  ../drivers/usb/gadget/dwc2_udc_otg.c:821:8: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
    reg = (struct dwc2_usbotg_reg *)pdata->regs_otg;
          ^

This changes regs_otg to a uintptr_t to ensure that it is large enough
to hold any valid pointer (and fix the associated warning).
