gpio: pca953x: Fix pca953x_gpio_set_config
pca953x_gpio_set_config is setup to support pull-up/down bias. Currently the driver uses a variable called 'config' to determine which options to use. Unfortunately, this is incorrect. This patch uses function pinconf_to_config_param(config), which converts this 'config' parameter back to pinconfig to determine which option to use.
