Subject: [PATCH v2 4/7] regulator: tps65215: Add chip_data struct for multi-PMIC support

'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.
