Changing struct member tps_driver_data.info to const for avoiding awkward type castings.

Subject: [PATCH 2/3] regulator: tps65023: Setting correct core regulator for tps65021
TPS65023 is using VDCDC1 as core regulator and TPS65021 is using VDCDC3.
Core-regulator, voltage-tables and size of voltage-table may differ between
different regulators. All those three is now passed as driver data.
