tty: serial: men_z135_uart.c: Updates for men_z135_uart

Version two of the updates for the men_z135_uart, incorporating Peter's review comments.

1/2: Use spin_lock_irq() in settermios() and spin_lock() in ISR to avoid
deadlocks.
2/2: Removes the double initialization of the port.lock spinlock.

Johannes Thumshirn (2):
tty: serial: men_z135_uart.c: Fix race between IRQ and set_termios()
tty: serial: men_z135_uart.c: Don't initialize port->lock

port->lock get's initialized in uart_add_one_port(), no need to do it in men_z135_probe().
