Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together.

odev -> pdev

You should write some scripts to compile-test these changes. Compilers
are good at catching these silly typos. Humans not so much.

Skipping this patch for now because of the bug pointed out by Thierry,
BTW rebase on my GPIO "devel" branch after I applied the
uncontroversial patches (most of them are obviously correct).

I know it is not super easy to build all of those systems so cold
coding is fine with me, I will find any remaining bugs for sure. :D

Yours,
Linus Walleij
