gpio: of: Handle fixed regulator flags properly
This fixes up the handling of fixed regulator polarity inversion flags: while I remembered to fix it for the undocumented "reg-fixed-voltage" I forgot about the official "regulator-fixed" binding, there are two ways to do a fixed regulator. The error was noticed and fixed.
