these patches add devicetree support for the Maxim MAX6639.
In addition, it includes optional regulator support for the fan-supply and
updates the URL to the datasheet.

Changes in v3:
- Remove warning if devm_regulator_get_optional returns an error.

Changes in v2:
- dt: Rename polarity to pwm-polarity.
- Remove unused platform_data header.
- Remove regulator enable/disable calls in pwm_store due to imbalance of
  calls.
- Move to strict per channel dt configuration without defaults.
