[PATCH] ARM: EXYNOS: Update secondary boot addr for secure mode

Browse Source 
(adapted from Sachin Kamat's patch)

Almost all Exynos-series of SoCs that run in secure mode don't need
additional offset for every CPU, with Exynos4412 being the only
exception.
(cherry picked from commit 10ba1ec8b021fda08d0342e19d86c1f319b0366d)
