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

Browse Source 
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.
