usb: gadget: add transfer_type in struct usb_ep for rockchip

Browse Source 
The usb gadget core set the chosen endpoint descriptor for
each endpoints in config_ep_by_speed(), however, we want
to get the transfer type of the endpoints earlier on the
rockchip platforms for usb controller initialization
(e.g. do tx fifos resize for rockchip usb dwc3 controller),
so this patch add transfer_type in the struct usb_ep, and
set the transfer_type in the usb_ep_autoconfig_ss().
