staging: iio: Introduce the use of devm_ioremap_resource

This patch introduces the use of devm_ioremap_resource. It does away
with call to request_mem_region and the error checking on
platform_get_resource. Also, the calls to free the allocated resources
like release_mem_region and iounmap are done away with. The ret variable
in the probe function is also eliminated. Also, a bug is fixed as the
goto in the error handling of request_mem_region should not have
called release_mem_region which releases a resource that has not been
allocated.
