serial: sh-sci: Replace direct stop_rx/stop_tx calls with port ops in sci_shutdown()

Replace direct calls to sci_stop_rx() and sci_stop_tx() with port ops
callbacks in sci_shutdown(). This enables the RSCI driver, which reuses
the SCI core but implements its own stop_rx and stop_tx logic, to reuse
sci_shutdown() without duplicating code.
