gpiolib: introduce fwnode_gpiod_get_index()
This introduces fwnode_gpiod_get_index() that iterates through common gpio suffixes when trying to locate a GPIO within a given firmware node. We also switch devm_fwnode_gpiod_get_index() to call fwnode_gpiod_get_index() instead of iterating through GPIO suffixes on its own.
