gpio: scmi: Add gpio_scmi driver
This provides GPIO support over SCMI. It is built on top of the
pinctrl-scmi driver. A typical device tree entry might look like
this:
gpio1 {
compatible = "scmi-pinctrl-gpio";
gpio-controller;
#gpio-cells = <2>;
ngpios = <10>;
gpio-ranges = <&scmi_pinctrl 0 8 4>,
<&scmi_pinctrl 4 12 1>,
<&scmi_pinctrl 5 15 1>,
<&scmi_pinctrl 6 17 4>;
pinctrl-names = "default";
pinctrl-0 = <&i2c2_pins>;
};
In this GPIO driver the one thing which is different is that in the
gpio-ranges the first numbers which represent how the pins are exposed
to the users have to start at zero and it can't have gaps.
