Siddharth Vadapalli c54c72dec7 usb: gadget: cdns3: Fix cdns3_ep_config() by setting ep.maxpacket 
The function cdns3_ep_config() calculates the maximum packet size based
on the Endpoint Type and the Gadget Speed and stores it in the variable
"max_packet_size". This value is then programmed in the USB Controller
for the corresponding Endpoint. This may result in a mismatch between
the maximum packet size programmed in the USB controller and the maximum
packet size seen by the UDC Core via "maxpacket" member of "struct usb_ep".
Additionally, since TD_SIZE is calculated in cdns3_ep_run_transfer() on the
basis of the maximum packet size stored in the "maxpacket" member of
"struct usb_ep", it may lead to an incorrect value of TD_SIZE when compared
with what the USB controller actually expects (max_packet_size).

Fix this.
