Add a driver for the TPS65185 regulator which provides the
comparatively high voltages needed for electronic paper displays.

Datasheet for the TPS65185 is at https://www.ti.com/lit/gpn/tps65185

To simplify things, include the hwmon part directly which is only
one temperature sensor and there are no other functions besides regulators
in this chip.
