ARM: shmobile: don't call platform_can_secondary_boot on UP
For rcar-gen2, we build the SMP files even for UP configurations,
and that just broke:
arch/arm/mach-shmobile/built-in.o: In function `shmobile_smp_init_fallback_ops':
pm-rcar-gen2.c:(.init.text+0x40c): undefined reference to `platform_can_secondary_boot'
This adds an compile-time check before the call to platform_can_secondary_boot,
turning the function into an empty stub for UP configurations.
