Simplify this function implementation by using the wrapper function
=E2=80=9Cdevm_platform_ioremap_resource=E2=80=9D instead of calling the fu=
nctions
=E2=80=9Cplatform_get_resource=E2=80=9D and =E2=80=9Cdevm_ioremap_resource=
=E2=80=9D directly.

* Thus reduce also a bit of exception handling code here.
* Delete the local variable =E2=80=9Cres=E2=80=9D.

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.
