usb: gadget: udc: renesas_usb3: fix number of the pipes
commit a58204ab91ad8cae4d8474aa0ba5d1fc504860c9 upstream.
This controller on R-Car Gen3 has 6 pipes that included PIPE 0 for
control actually. But, the datasheet has error in writing as it has
31 pipes. (However, the previous code defined 30 pipes wrongly...)
Anyway, this patch fixes it.
