[1/2] regulator: palmas: Correct TPS659038 register definition for REGEN2

Commit Message

J, KEERTHY March 17, 2015, 10:26 a.m. UTC

The register offset for REGEN2_CTRL in different for TPS659038 chip as when
compared with other Palmas family PMICs. In the case of TPS659038 the wrong
offset pointed to PLLEN_CTRL and was causing a hang. Correcting the same.

Tested for the regulator enumerations on DRA7 and BEAGLE-X15 boards.
