[PATCH v2 2/4] dt-bindings: net: nfc: samsung,s3fwrn5: Add pvdd-supply

[Asdlerto Korry via B4 Relay <devnull+korryasdlerto.gmail.com@kernel.org>]

From: Asdlerto Korry <korryasdlerto@gmail.com>

The PVDD pin of the S3FWRN5 has to be powered before the chip is
enabled. On some boards, like the Samsung Galaxy M52 5G, this supply
is switched by a SoC GPIO. Document it, so that the regulator can be
handed to the driver instead of being kept always on.
