staging: emxx_udc: add missing usb_ep_set_maxpacket_limit()

Since maxpacket_limit was introduced all UDC drivers should use
usb_ep_set_maxpacket_limit() function instead of setting maxpacket value
manually. ep.maxpacket_limit contains actual maximum maxpacket value
supported by hardware which is needed by epautoconf.
