regulator: tps65219: Add support for TPS65215 regulator resources
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.
