usb: chipidea: udc: limit usb request length to max 16KB
To let the device controller work properly on short packet limitations,
one usb request should only correspond to one dTD. Then every dTD will
set IOC. In theory, each dTD support up to 20KB data transfer if the
offset is 0. Due to we cannot predetermine the offset, this will limit
the usb request length to max 16KB. This should be fine since most of
the user transfer data based on this size policy.
