If CONFIG_SMP=n, building a kernel for R-Car Gen2 fails with:
arch/arm/mach-shmobile/setup-rcar-gen2.o: In function `rcar_gen2_timer_init':
setup-rcar-gen2.c:(.init.text+0x30): undefined reference to `secure_cntvoff_init'
Indeed, on R-Car Gen2 SoCs, secure_cntvoff_init() is not only needed for
secondary CPUs, but also for the boot CPU. This is most visible on SoCs
with Cortex A7 cores (e.g. R-Car E2, cfr. commit 9ce3fa6816c2fb59 ("ARM:
shmobile: rcar-gen2: Add CA7 arch_timer initialization for r8a7794")),
but Cortex A15 is affected, too.
Fix this by always providing secure_cntvoff_init() when building for ARM
V7.
