usb: renesas_usbhs: Use dmac only if the pipe type is bulk
commit 700aa7ff8d2c2b9cc669c99375e2ccd06d3cd38d upstream.
This patch fixes an issue that isochronous transfer's data is possible to
be lost as a workaround. Since this driver uses a workqueue to start
the dmac, the transfer is possible to be delayed when system load is high.
