Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@

- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
   ... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
   ... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
   e = devm_ioremap_resource(e1, res);
// </smpl>
