Define enum PMUX_FUNC_DEFAULT, which indicates that a table entry passed to pinmux_config_pingrp()/pinmux_config_pingrp_table() shouldn't change the mux option in HW. For pins that will be used as GPIOs, the mux option is irrelevant, so we simply don't want to define any mux option in the pinmux initialization table.
