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.
