davinci: da850/omap-l138 evm: account for DEFDCDC{2,3} being tied high
Per the da850/omap-l138 Beta EVM SOM schematic, the DEFDCDC2 and
DEFDCDC3 lines are tied high. This leads to a 3.3V IO and 1.2V CVDD
voltage.
Pass the right platform data to the TPS6507x driver so it can operate
on the DEFDCDC{2,3}_HIGH register to read and change voltage levels.
