debug_uart: Support board-specific UART initialisation
Some boards need to set things up before the debug UART can be used. On these boards a call to debug_uart_init() is insufficient. When this option is enabled, the function board_debug_uart_init() will be called when debug_uart_init() is called. You can put any code here that is needed to set up the UART ready for use, such as set pin multiplexing or enable clocks.
