usb: renesas_usbhs: fix usbhs_pipe_clear() for DCP PIPE
Since the DCPCTR doesn't have the ACLRM bit, the usbus_pipe_clear() should not call the usbhsp_pipectrl_set() with ACLRM. So, this patch fixes this issue to add the usbhs_fifo_clear_dcp() in fifo.c because the controller needs the CFIFO to clear the the DCP PIPE.
