hwrng: ixp4xx - Make use of the helper function devm_platform_ioremap_resource()
Use the devm_platform_ioremap_resource() helper instead of calling platform_get_resource() and devm_ioremap_resource() separately Signed-off-by: Cai Huoqing <caihuoqing@baidu.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
