In struct mxser_port, all the UART registers and masks, and the xon/xoff
character are stored into int. Let's re-type all these as UART registers
are 8bit (u8) and xon/xoff character is an unsigned char (cc_t in
ktermios).
This save some bytes in memory, but more importantly the change makes it
what it really is.
