[PATCH 1/3] m32r: Use generic PREEMPT config

[Frederic Weisbecker <fweisbec@gmail.com>]

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'

-	  This option reduces the latency of the kernel when reacting to

-	  be preempted even if it is in kernel mode executing a system call.
