[PATCH] RTC class uses subsys_init

This makes RTC core components use "subsys_init" instead of "module_init", as
appropriate for subsystem infrastructure.  This is mostly useful for
statically linking drivers in other parts of the tree that may provide an RTC
interface as a secondary functionality (e.g.  part of a multifunction chip);
they won't need to worry so much about drivers/Makefile link order.
