Breaking change: Update of GPIO special function mapping (#1204)

The API `uCellGpioConfigSpecialFunction()` has a breaking change to its parameter `specialFunction ` due to the update of `uCellGpioSpecialFunction_t` enum.
A new parameter (`U_CELL_GPIO_SPECIAL_FUNCTION_INPUT_WITH_INTERRUPT`) is added and few values are remapped.
