Subject: [PATCH 2/2] regulator: bd71828: Fix .n_voltages settings

Current .n_voltages settings do not cover the latest 2 valid selectors,
so it fails to set voltage for the hightest voltage support.
The latest linear range has step_uV = 0, so it does not matter if we
count the .n_voltages to maximum selector + 1 or the first selector of
latest linear range + 1.
To simplify calculating the n_voltages, let's just set the
.n_voltages to maximum selector + 1.

Fixes: 522498f8cb8c ("regulator: bd71828: Basic support for ROHM bd71828 PMIC regulators")
