gpio: pca953x: disable regmap locking for automatic address incrementing



It's a repetition of the commit aa58a21a
  ("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.
