Let's do that way you are preparing a branch somewhere and anounce
here as an RFC, since this was neither tested nor correct.
And selling point for many of them is not true: it doesn't make any
difference in the size in code, but increases a time to run
(devm_ioremap_resource() does more than plain devm_iomap() call).
