I don't like the state string.
Instead have boolean properties for all states.
line_b {
gpio-hog;
gpios = <6 0>;
output-low;
line-name = "foo-bar-gpio";
}
Then use of_property_read_bool() in the code to check which
state is to be selected intially. You can check that no mutually
exclusive state are selected, I don't like that an arbitrary string
select the state like that, if we do it that way an enumerator would
be better, I prefer bools.
