odule, the linking of the kernel
fails with:

drivers/built-in.o: In function `_hardware_dequeue':
drivers/usb/chipidea/udc.c:527:
    undefined reference to `usb_gadget_unmap_request'
drivers/usb/chipidea/udc.c:1269:
    undefined reference to `usb_gadget_unmap_request'

drivers/usb/chipidea/udc.c:1774:
    undefined reference to `usb_add_gadget_udc'

This patch changes the dependencies, so that udc support can only be
activated if the linux gadget support (USB_GADGET) is builtin or both
chipidea driver and USB_GADGET are modular. Same dependencies for the
chipidea host support and the linux host side USB support (USB).

While there, fix the indention of chipidea the help text.
