When of_pwm_get() is called without connection ID it returns
-ENOENT when the 'pwms' property doesn't exists or is an empty entry.
However when a connection ID is given and the 'pwm-names' property
doesn't exists or doesn't contains the requested name it returns
-ENODATA or -EINVAL.
To get a consistent return value with both code paths we must return
-ENOENT when of_property_match_string() fails.
