usb: renesas_usbhs: fixup dma transfer stall
renesas_usbhs driver can switch DMA/PIO transfer by using handler, and each handler have push/pop direction. But unfortunately, current dma push handler didn't a path which calls usbhs_pipe_enable(). Thus, dma transfer never happened. this patch fixes it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
