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

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.

Applied to linux-pm.git/bleeding-edge and will be moved to linux-next after
build testing.

Thanks,
