Isolate all changes involving TPS65215 regulator desc and range resources.

- 'chipid' will identify which PMIC to support, and the corresponding
  chip_data struct element to use in probe(). The chip_data struct is
  helpful for any new PMICs added to this driver. The goal is to add future
  PMIC info to necessary structs and minimize probe() function edits.

- The probe() will now loop through common (overlapping) regulators first,
  then device-specific structs identified in the chip_data struct.

- Add TI TPS65215 PMIC to the existing platform_device_id struct, so the
  regulator probe() can handle which PMIC chip_data information to use.
