Use devm_iio_device_register, which removes the tsl2772_remove
function.

Use devm_add_action_or_reset to call tsl2772_chip_off
when the device is removed.
This also fixes the issue that the chip is turned off
before the device is unregistered.
Not marked for stable as fairly hard to hit the bug and
this is in the middle of a set making other cleanups
to the driver. Hence will probably need explicit backporting.

This patch adds support for the regulator framework to the tsl2772
driver. Driver was tested using a LG Nexus 5 (hammerhead) phone with
the two regulators and on a Raspberry Pi 2 without any regulators
controlling the power to the sensor.

This patch adds support for optionally reading the proximity led diode
and current settings from device tree. This was tested using a LG
Nexus 5 (hammerhead) which requires a different diode than the driver
default for the IR LED.

It may be possible for tsl2772_get_lux to return a zero lux value
and hence a division by zero can occur when lux_val is zero. Check
for this case and return -ERANGE to avoid the division by zero.
