Note that error handling on the result of a call to platform_get_resource()
is unneeded when the value is passed to devm_ioremap_resource(), so remove
it. Then use the helper function that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]
