[PATCH 1/2] tty: serial: imx: add lock for registers save/restore

In noirq suspend/resume stage with no_console_suspend enabled, .imx_console_write() may be called to print out log_buf message by .printk(), so there will be race condition between .imx_console_write() and .serial_imx_save/restore_context(), need to add lock to protect the registers save/restore
