MLK-17218 tty: serial: imx: add lock for register save/restore The driver save/restore registers in system suspend/resume noirq stage to support no_console_suspend in power lost case. In noirq stage with no_console_suspend, .imx_console_write() _maybe_ called to print out log_buf message in .printk() or console_unlock() called by other drivers. It should add port.lock to protect the registers save/restore in noirq stage since .imx_console_write() also access them.
