usb: renesas_usbhs: tidyup original usbhsx_for_each_xxx macro
Current usbhsx_for_each_xxx macro will read out-of-array's memory after last loop operation. It was not good C language operation, and the binary which was compiled by (at least) gcc 4.8.1 is broken This patch tidyup these issues Reported-by: Yusuke Goda <yusuke.goda.sx@renesas.com> Reviewed-by: Takashi Yoshii <takashi.yoshii.zj@renesas.com> Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
