[PATCH v4 36/36] iio: temperature: hid-sensor-temperature: drop hid_sensor_remove_trigger() using devm API

[Sanjay Chitroda <sanjayembeddedse@gmail.com>]

From: Sanjay Chitroda <sanjayembeddedse@gmail.com>

Use devm_hid_sensor_setup_trigger() to automatically release resource
during fail, unbind or removal of driver using devres framework.

This simplify the setup, remove goto, avoid manual resource cleanup in
teardown path.
