exynos: secondary_startup endian fix
If kernel operates in BE mode on board that has LE bootloader/rom code, we need
to switch CPU to operate in BE mode as soon as possible. generic
secondary_startup that is called from exynos specific secondary startup code
will do the switch, but we need it to do earlier because exynos specific
secondary_startup code works with BE data.
