tty: serial: 8250_core: provide a function to export uart_8250_port
There is no way to access a struct uart_8250_port for a specific line. This is only required outside of the 8250/uart callbacks like for devices' suspend & remove callbacks. For those the 8250-core provides a wrapper like serial8250_unregister_port() which passes the struct to the proper function based on the line argument. For run time suspend I need access to this struct not only to make serial_out() work but also to properly restore up->ier and up->mcr.
