[PATCH v3 0/2] ns16550-related patches

[Antony Pavlov]

This patch series consist of two ns16550-related patches.

The 1st one adds the flag (NS16650_FLAG_DISABLE_FIFO) in internal
ns16550 data structure to recognise UART with broken FIFO
(or UART without FIFO at all) and the code to use this flag.
The flag can be set in board-related code.

The 2nd one use the fact that ns16550_serial_init_port() and
ns16550_setbaudrate() functions have many common code.
It change the most of ns16550_serial_init_port() code for
one ns16550_setbaudrate() call.
