[PATCH] drivers: cpuidle: kirkwood: fix coccicheck warnings

From: Silviu-Mihai Popescu
Date: Thu Mar 21 2013 - 20:13:13 EST

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.
