[PATCH 6.12.y-cip 10/38] serial: sh-sci: Replace direct stop_rx/stop_tx calls with port ops in sci_shutdown()

commit 13af95c7f602cf3644f3145530ec2e80a88659eb upstream.

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.
