This regulator is, for some reason, currently attached to the virtual omapdss device, instead of the SDI device. This does not work for DT, as the regulator mappings need to be described in the DT data, and the virtual omapdss device is not present there. Fix the issue by acquiring the regulator in the SDI device. To retain compatibility with the current board files, the old method of getting the regulator is kept. The old method can be removed when the board files have been changed to pass the regulator to SDI.
