We introduce a macro FUNCTION_EX here, the main motivation is trying to have the possibility to expand the macro with the same of the '.name' number but different multiple '.groups/.num_groups' numbers. With this change, the meson pinctrl drivr is capable of have one uniform 'function' name but with different pin 'groups', as we face the sitiuation that two pin groups may live inside different hardware domain (EE vs AO domain), which mean we couldn't put them in one single group.
