drivers: provide devm_platform_get_and_ioremap_resource()
Since commit "drivers: provide devm_platform_ioremap_resource()", it was wrap platform_get_resource() and devm_ioremap_resource() as single helper devm_platform_ioremap_resource(). but now, many drivers still used platform_get_resource() and devm_ioremap_resource() together in the kernel tree. The reason can not be replaced is they still need use the resource variables obtained by platform_get_resource(). so provide this helper.
