TPS gpio now controls a 5v 500mA TL5209 regulator which may be supply
a fan (such as AFB02505HHB) over J1 connector for various purposes.
Provide device tree node to enable the same.

Depends on the following:

enable and disable can be controlled by
echo '1' > /sys/class/hwmon/hwmon0/fan1_target
and
echo '0' > /sys/class/hwmon/hwmon0/fan1_target
requires CONFIG_GPIO_PALMAS and CONFIG_SENSORS_GPIO_FAN to be operational

- Sanitized outlook-ified name back to normal ;)
- removed unnecessary pinctrl-names property.

Depends on the following:

enable and disable can be controlled by (post the RPM, it finds
closest match - even a 1 will do)

and
echo '0' > /sys/class/hwmon/hwmon0/fan1_target
