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.

V2: review comment updates
	review comments update
		- Sanitized outlook-ified name back to normal ;) 
		- removed unnecessary pinctrl-names property.
V1: https://patchwork.kernel.org/patch/5444911/


Depends on the following:
https://patchwork.kernel.org/patch/5439201/
https://patchwork.kernel.org/patch/5439191/

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

echo '13000' > /sys/class/hwmon/hwmon0/fan1_target
and
echo '0' > /sys/class/hwmon/hwmon0/fan1_target

Test log: http://slexy.org/view/s2T0ajh46z

requires CONFIG_GPIO_PALMAS and CONFIG_SENSORS_GPIO_FAN to be operational
Applies on 
https://git.kernel.org/cgit/linux/kernel/git/tmlind/linux-omap.git/log/?h=omap-for-v3.19/dt-v2
