[PATCH 4.7 039/143] usb: renesas_usbhs: Fix receiving data corrupt on R-Car Gen3 with dmac

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

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

From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>

commit 772ce81264b179c0e61340998e3b29e900b2fa6d upstream.

Since R-Car Gen3 SoC has the USB-DMAC, this driver should set
dparam->has_usb_dmac to 1. Otherwise, behavior of this driver and
the usb-dmac driver will be mismatch, then sometimes receiving data will
be corrupt.
