This will be useful for tty port helpers. These flags are handled by the helpers instead. So we create a new function uart_port_startup without touching these flags there. And we keep uart_startup with the exact behavior as before. We need that one because we start/stop the device from other paths than open/close/hangup.

We will need this for hangup and close port helpers. We don't need to touch DTR/RTS registers in uart_port_shutdown. They are set to off from port_close_start properly already. Also we don't need to pin the TTY_IO_ERROR bit. This will be done in close/hangup paths. We leave uart_shutdown as is, because it is used (and will be) from several paths now. Like from suspend. The point is to not touch ASYNC_INITIALIZED bit. It will be set (and checked) properly by the tty port helpers.

There were many errors fixed recently. Extract the tty driver lookup from tty_open to a separate function. This reduces the fail paths significantly and makes tty_open more readable. In the next patch we will move the fail path handling to the end of the function.

We have the tty directly, not its driver and index. So this will reside in a separation function. In the next patch, the rest will be moved to another function. So now we set neither driver nor index. Hence we need to init driver and check whether we are supposed to put a ref of that.
