ARM: mach-shmobile: Fix build when SMP is enabled and EMEV2 is not enabled

Build failed, when SMP is enabled and EMEV2 is not enabled.

arch/arm/mach-shmobile/built-in.o: In function `shmobile_platform_cpu_kill':

This is the cause by when EMEV2 is disabled, that the check by OF of EMEV2 is
performed in platsmp.c.
This patch revise what the function about EMEV2 may not be used in this file,
when EMEV2 is not enabled.
