[PATCH v3 3/9] iio: hid-sensors: introduce device managed API

[Sanjay Chitroda]

From: Sanjay Chitroda <sanjayembeddedse@xxxxxxxxx>

hid_sensor_setup_trigger() is common API used for the HID IIO drivers,
prepare devm API devm_hid_sensor_setup_trigger() to acquire resource
during setup and release using device managed framework during drivers
fail, unbind or remove path.

Register action with devm_add_action_or_reset() to release resource with
devres framework.
