[IA64] Include Kconfig.preempt
arch/ia64/Kconfig failed to include kernel/Kconfig.preempt that meant it did not support PREEMPT_VOLUNTARY and PREEMPT_BKL (inadvertently). This was recently noticed when the newly-added PREEMPT_NOTIFIERS in Kconfig.preempt that was "select"ed from drivers/kvm/Kconfig (therefore) started giving bogus warnings ('select' used by config symbol 'KVM' refers to undefined symbol 'PREEMPT_NOTIFIERS') on ia64 builds. So let's remove the open-coded definition of CONFIG_PREEMPT in arch/ia64/Kconfig and replace it with just including Kconfig.preempt instead, like the other archs do.

This option it useful to enable this feature on older BIOS's as well.
You can also enable this by using boot command line option force_cpei=1.
-config PREEMPT
- bool "Preemptible Kernel"
- 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.
