crypto: picoxcell - Use devm_ioremap_resource()
Use devm_ioremap_resource() in order to make the code simpler, and remove redundant return value check of platform_get_resource() because the value is checked by devm_ioremap_resource(). Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
