[PATCH 1/4] ARM: dts: helios4: add vcc-supply to EEPROM

The at24 driver requests a 'vcc' supply for the EEPROM, producing
'supply vcc not found, using dummy regulator' at boot when the
property is missing.

The EEPROM sits on the Helios 4 and is powered by the
same always-on 3.3V rail used by other on-board I2C devices.
Add vcc-supply = <&reg_3p3v> to silence the warning.
