[PATCH v8 6/8] ARM: EXYNOS: remove secondary startup initialization from smp_prepare_cpus

[Pankaj Dubey <pankaj.dubey@samsung.com>]

We are taking care of setting secondary cpu boot address in
exynos_boot_secondary just before sending ipi to secondary CPUs,
so we can safely remove this setting from smp_prepare_cpus.
