ARM: dts: helios4: add vcc-supply to GPIO expander

Browse source

The pca953x driver requests a 'vcc' supply, producing:
  pca953x 0-0020: supply vcc not found, using dummy regulator

The PCA9655 (PCA9555-compatible) expander is powered by the same
always-on 3.3V rail as the other I2C devices on the bus.  Add
vcc-supply = <&reg_3p3v> to silence the warning.
