usb: gadget: imx_udc: make it depend on BROKEN

that driver hasn't been maintained for quite
some time, at least since e083000 (ARM:
imx: dynamically allocate imx_udc device).

Because of that, and because driver doesn't
even compile with allyesconfig and allmodconfig,
we're making it depend on BROKEN.
