Thanks everyone for the comments. I apply most of the comments on version 1
but there is still a pending point with the Jiri comment about the safety of:
struct tty_struct *tty = p->port.state->port.tty;
I thought about adding a check with tty_port_initialized() before accessing
the pointer, but I saw some other places where that same pointer is accessed
without further protection, at least from what I see.

Thanks for the update. Unfortunately I'm a bit busy with other prioritized
stuff, but I will review this next week.

Changes from v1 to v2:
- Use UART_CAP_NOTEMT instead of UART_CAP_TEMT
- Use some predefined macro to reduce magicness
- Reset active_timer in temt timer handler
- add uart_get_byte_size
- set UART_CAP_NOTEMT in uart_config for PORT_16550A_FSL64
- Improve commit messages
- Improve grammar and spelling
- Add Giulio and Heiko SoB to reflect previous work
