arm: am33xx: Make pin multiplexing functions optional
This patch provides default implementations of the two functions set_uart_mux_conf and set_mux_conf_regs. Hence boards not using them do not need to provide their distinct empty definitions. Signed-off-by: Felix Brack <fb@ltec.ch> Reviewed-by: Tom Rini <trini@konsulko.com>
