driver/uart: Introduce a way for mainboard to override the baudrate
The rationale is to allow the mainboard to override the default
baudrate for instance by sampling GPIOs at boot.
A new configuration option is available for mainboards to select
this behaviour. It will then have to define the function
get_uart_baudrate to return the computed baudrate.
