Subject: [PATCH 1/2] dt-bindings: nfc: nxp-nci: document pvdd-supply

PN547/553, QN310/330 chips on some devices require a pad supply voltage
(PVDD). Otherwise, the NFC won't power up.

Document support for pad supply voltage pvdd-supply that is enabled by
the nxp-nci driver so that the regulator gets enabled when needed.
