serial: core: Privatize tty->hw_stopped tty->hw_stopped is not used by the tty core and is thread-unsafe; hw_stopped is a member of a bitfield whose fields are updated non-atomically and no lock is suitable for serializing updates. Replace serial core usage of tty->hw_stopped with uport->hw_stopped. Use int storage which works around Alpha EV4/5 non-atomic byte storage, since uart_port uses different locks to protect certain fields within the structure.
