Convert the driver to DTS-only version. This simplifies a little the code: 1. No dead (unused) entries in platform_data structure. 2. More code removed. 3. Regulator driver does not depend on allocated memory from MFD driver. 4. It makes also easier extending the regulator driver. Add to the max77686 MFD driver dependency on CONFIG_OF because without DTS the regulator drivers won't bind.
