usb: renesas_usbhs: add usbhs_pipe_clear_without_sequence() function
This patch adds usbhs_pipe_clear_without_sequence() function. The controller has the pipe buffer and the PIPEnCTR.ACLRM can clear it completely. But, it's also clear the data sequence. So, the driver needs to get the sequence before. Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
