usb: renesas_usbhs: care pipe sequence
driver has to re-use the limited pipe for each device/endpoint when it is USB host hub mode, since number of pipe has limitation. Then, each pipe should care own pipe sequence for next packet. This patch adds sequence control. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
