sched/preempt: Tell about PREEMPT_DYNAMIC on kernel headers
Displaying "PREEMPT" on kernel headers when CONFIG_PREEMPT_DYNAMIC=y can be misleading for anybody involved in remote debugging because it is then not guaranteed that there is an actual preemption behaviour. It depends on default Kconfig or boot defined choices. Therefore, tell about PREEMPT_DYNAMIC on static kernel headers and leave the search for the actual preemption behaviour to browsing dmesg.
