dt-bindings: gpio-regulator: add vin-supply property support

This is same scheme as fixed-regulator. 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.
