Why? We can see what you did here, but commit msg should explain why you
do it...

Best regards,

Sorry, I didn't describe this commit message clearly.

In the future, meson-s4.dtsi will have some nodes that need
to use the meson-s4-gpio.h file.

e.g.
	(1) Bluetooth enable pin:
		bt_en-gpios = <&gpio GPIOX_17 GPIO_ACTIVE_HIGH>;
	(2) Audio mute pin:
		spk_mute-gpios = <&gpio GPIOH_8 GPIO_ACTIVE_LOW>;
	(3) ...

So, this patch was born.

Best regards,
Huqiang

We understand, but since the Upstream linux codebase want to avoid dead code
as much as possible, please defer this patch when node will actually use these gpio defines.

Thanks for your explanation, I know what to do.
