usb: gadget: ci13xxx: Update usb_eps' maxpacket_limit 



Newly added maxpacket_limit field in usb_ep must be
initialized by UDC drivers to set maximum packet size
limit for endpoint using usb_ep_set_maxpacket_limit().
If maxpacket_limit is not specified then usb_ep_autoconfig
fails while checking wMaxPacketSize against maxpacket_limit
for ISOC and interrupt endpoints.
