gpio: pca953x: disable regmap locking for automatic address incrementing
It's a repetition of the commit aa58a21ae378 ("gpio: pca953x: disable regmap locking") which states the following: This driver uses its own locking but regmap silently uses a mutex for all operations too. Add the option to disable locking to the regmap config struct.
