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'

- help
- 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.
