This adds the cpu-supply DT property to the cpu0 DT node needed by
the board to adapt the regulator voltage depending on the currently use
OPP.

This hasn't been tested on the board but it is what I understand from the
schematics[1] of the board.

Stefan (or anyone owning this board), could you test this series of patch on the
Olinuxino A33, test CPUfreq on it and tell us if it works? Thanks!
