[PATCH 1/2] regulator: mt6370: Use 'fwnode_gpiod_get_index' to fix gpio parsing

[cy_huang]

From: ChiYuan Huang <cy_huang@xxxxxxxxxxx>

>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.
