commit 895ee5aefb upstream.

This reverts commit 3c5b006f3e.

gadget_is_{super|dual}speed() API check UDC controller capitblity. It
should pass down highest speed endpoint descriptor to UDC controller. So
UDC controller driver can reserve enough resource at check_config(),
especially mult and maxburst. So UDC driver (such as cdns3) can know need
at least (mult + 1) * (maxburst + 1) * wMaxPacketSize internal memory for
this uvc functions.
