Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

All TPS51632 registers are not readable/writable and
non-volatiles.

Add property of the registers whether it is readable/writable
or volatile for regmap framework.

If pdata->base_voltage_uV is missing or the settings of pdata->base_voltage_uV
and pdata->max_voltage_uV are out of range, TPS51632_VOLT_VSEL macro
returns wrong vsel.

Thus add checking [base|max]_voltage_uV pdata settings in probe.

When tps->enable_pwm_dvfs is true, write to TPS51632_VOLTAGE_BASE_REG rather
than TPS51632_VOLTAGE_SELECT_REG.

The TPS51632 is a driverless step down controller with
serial control. Advanced features such as D-Cap+
architecture with overlapping pulse support and OSR
overshoot reduction provide fast transient response,
lowest output capacitance and high efficiency.
The TPS51632 supports both I2C and DVFS interfaces
(through PWM) for dynamic control of the output voltage
and current monitor telemetry.
Add regulator driver for TPS51632.
