Subject: [PATCH v3 0/2] NFC: nxp-nci: Add pad supply voltage pvdd-supply

v3: Fix weird wrapping and drop another unnecessary nxp_nci_i2c_poweroff()
v2: Use dev_err_probe() and drop unnecessary nxp_nci_i2c_poweroff()

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

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