gpio: pca953x: Perform basic regmap conversion Convert the driver to use regmap to access the chips. Due to the convoluted register mapping scheme, implement read/write/volatile check functions that untangle the mess and perform check accordingly. This patch does not zap the internal register cache of the PCA953x driver, nor does it push the regmap access down into the gpiochip accessors to simplify the review. All that is in subsequent patches.
