usb: renesas_usbhs: use PIPEnCLR.ACLRM instead of {C,Dn}FIFOCTR.BCLR in usbhs_pkt_pop()

This patch uses usbhs_pipe_clear_without_sequence() instead of
usbhsf_fifo_clear() because usbhsf_fifo_clear() may not clear the pipe
buffer completely. This patch also changes the clearing condition from
DMA only to both DMA and PIO.
