Some of kernel driver uses the IIO framework to get the sensor
value via ADC or IIO HW driver. The client driver get iio channel
by iio_channel_get() and release it by calling iio_channel_release().

Add resource managed version (devm_*) of these APIs so that if client
calls the devm_iio_channel_get() then it need not to release it explicitly,
it can be done by managed device framework when driver get un-binded.

This reduces the code in error path and also need of .remove callback in
some cases.

Please provide at least one example of code that uses this API.

Most of client for this APIs are in other subsystem.
When I was working on the patch
[PATCH 2/2] thermal: generic-adc: Add ADC based thermal sensor driver

if I have devm_iio_channel_get() then I can get .remove callback at all.

I did not use this new APIs in my patch because they are in different subsystem.
