Simplify this function implementation by using the wrapper function
“devm_platform_ioremap_resource” instead of calling the functions
“platform_get_resource” and “devm_ioremap_resource” directly.

* Thus reduce also a bit of exception handling code here.
* Delete the local variable “res”.

This issue was detected by using the Coccinelle software.

* Updates for three modules were split into a separate patch for each driver.

* The commit description was adjusted.
