sched: dynamic: Simplify preempt model accessors
PREEMPT_DYNAMIC is now limited to the FULL and LAZY preemption models.
When CONFIG_PREEMPT_DYNAMIC=y, the NONE and VOLUNTARY models cannot be
used, and neither CONFIG_PREEMPT_NONE nor CONFIG_PREEMPT_VOLUNTARY can
be selected.
Simplify the preempt model accessors accordingly: remove the out-of-line
implementations of preempt_model_none() and preempt_model_voluntary(),
and remove the preempt_dynamic_{none,voluntary} values.
There are no current users of preempt_model_voluntary(), but I've kept
it around for consistency, with every scheduler model having its own
preempt_model_*() accessor.
