usb: gadget: udc: renesas_usb3: fix number of the pipes

Browse Source 
commit a58204ab91 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.
