regulator: gpio: Add input_supply support in gpio_regulator_config
This is simillar as fixed-regulator.
Used to extract regulator parent from the device tree.
Without that property used, the parent regulator can be shut down (if not an always on).
Thus leading to inappropriate behavior:
On am62-SP-SK this fix is required to avoid tps65219 ldo1 (SDMMC rail) to be shut down after boot completion.
