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'

		This option reduces the latency of the kernel when reacting to
		real-time or interactive events by allowing a low priority process to
		be preempted even if it is in kernel mode executing a system call.
		This allows applications to run more reliably even when the system is
		under load.

		Say Y here if you are building a kernel for a desktop, embedded
		or real-time system. Say N if you are unsure.
