Subject: [PATCH v2 13/14] regulator: bd96801: Support ROHM BD96806 PMIC

The ROHM BD96806 is from the software perspective almost identical to
the ROHM BD96802. The main difference is different voltage tuning
ranges.

Add support differentiating these PMICs and provide correct voltages
for both models.
