From: ChiYuan Huang <cy_huang@richtek.com>
From the common binding, 'enable-gpio' or 'enable-gpios' are all well for external 'enable' gpio.
'gpiod_get_from_of_node' only parse the 'enable' property, it need to add the gpio suffix. It's more convenient to use fwnode_gpiod_get_index. Although fwnode parsing is not preferred, but 'of_parse_cb' already can guarantee the callback will only be used by regulator of_node parsing.
