regulator: arizona-ldo1: Fix handling of GPIO 0
The LDO1 driver is using the arizona_of_get_named_gpio helper function
which will return 0 if an error was encountered whilst parsing the GPIO,
as under the pdata scheme 0 was not being treated as a valid GPIO.
However, since the regulator framework was expanded to allow the use of
GPIO 0 this causes us to attempt to register GPIO 0 when we encountered
an error parsing the device tree.
This patch uses of_get_named_gpio directly and sets the
ena_gpio_initialized flag based on the return value.
Fixes: 1de3821ace82 ("regulator: Set ena_gpio_initialized in regulator drivers")
