rtc: constify rtc_class_ops structures

Declare rtc_class_ops structures as const as they are only passed
as an argument to the function devm_rtc_device_register. This argument
is of type const struct rtc_class_ops *, so rtc_class_ops structures
having this property can be declared const.
Done using Coccinelle:

identifier i;

static struct rtc_class_ops i@p = {...};
