regulator: ti-abb: simplify platform_get_resource_byname/devm_ioremap_resource

Browse Source 
Remove unneeded error handling on the result of a call to
platform_get_resource_byname 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,e,e1;
expression ret != 0;
identifier l;
@@

  res = platform_get_resource_byname(...);
- if (res == NULL) { ... \(goto l;\|return ret;\) }
  e = devm_ioremap_resource(e1, res);
// </smpl>
