A wrapper function is available since the commit 7945f929f1a77a1c8887a97ca07f87626858ff42
("drivers: provide devm_platform_ioremap_resource()").

* Thus reuse existing functionality instead of keeping duplicate source code.

* Delete a local variable which became unnecessary with this refactoring.


This issue was transformed by using the Coccinelle software.
