of: Add of_property_match_string() to find index into a string list
Add a helper function for finding the index of a string in a string list property. This helper is useful for bindings that use a separate *-name property for attaching names to tuples in another property such as 'reg' or 'gpios'. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
