m32r: Use generic PREEMPT config
Use the generic preempt config definition in m32r instead of
using a custom one.
This also makes it handle the new CONFIG_PREEMPT_COUNT that
need to be selected by CONFIG_PREEMPT.
Without that it breaks
kernel/sched.c: In function 'preempt_schedule':
kernel/sched.c:4364: error: implicit declaration of function 'add_preempt_count_notrace'
kernel/sched.c:4366: error: implicit declaration of function 'sub_preempt_count_notrace'
