If the signal is routed through IO MUX to the pin, then only needs to call `gpio_iomux_input` to select the IO MUX function index and direct the signal to IO MUX. Input will be enabled for the IO internally.

If the signal is routed through GPIO Matrix to the pin, then call `gpio_matrix_input` to enable the input and connect the signal to the pin.
When a peripheral driver does de-initialization, to de-configure the pin as the peripheral signal input, use `esp_rom_gpio_connect_in_signal` to connect the signal to CONST_ONE or CONST_ZERO, so that it is disconnected from the pin. It is not desired to call `gpio_input_disable`, because there might be other drivers still using this pin as an input.
