pinctrl: pinconf-generic: Add API for pinmux propertity in DTS file
When describing pin mux func through pinmux propertity,
a standard API is added for support. The pinmux contains pin
identification and mux values, which can include multiple
pins. And groups configuration use other word. DTS such as:
func-name {
group_alias: group-name{
pinmux= <pin_id << 8 | mux_value)>,
<pin_id << 8 | mux_value)>;
bias-pull-up;
drive-strength-microamp = <4000>;
};
};
