uart_xmit_advance() provides a common way on how to advance
the Tx queue. Use it for the sake of unification and robustness.

Please note though that I already have patches for almost all these but
I've not just submitted the remaining ones yet.

My interest only for a limited scope of 8250 compatible UARTs, I have sent
just a couple of patches and I don't think I will send more.

not in tty-next.
