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.
Fixes: 15add06841a3 ("gpio: pca953x: add ->set_config implementation")
