4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Yoshihiro Shimoda <[email protected]>

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.

peripheral controller")
