The secure_cntvoff_init() function is not available without CONFIG_SMP,
leading to a link error on shmobile:
arch/arm/mach-shmobile/setup-rcar-gen2.o: In function `rcar_gen2_timer_init':
setup-rcar-gen2.c:(.init.text+0x18): undefined reference to `secure_cntvoff_init'
>From the description in commit 3fd45a136ff6 ("ARM: shmobile: rcar-gen2:
Make sure CNTVOFF is initialized on CA7/15"), I understand that we
don't need to call it on non-SMP builds because the boot CPU is always
initialized by common code, so we can simply avoid the reference by
checking for CONFIG_SMP.
