usb: gadget: udc: renesas_usb3: fix maxpacket size of ep0

commit dfe1a51d2a36647f74cbad478801efa7cf394376 upstream.

This patch fixes an issue that maxpacket size of ep0 is incorrect
for SuperSpeed. Otherwise, CDC NCM class with SuperSpeed doesn't
work correctly on this driver because its control read data size
is more than 64 bytes.
