ARM: HYP/non-sec: relocation before enable secondary cores
If CONFIG_ARMV7_PSCI is not defined and CONFIG_ARMV7_SECURE_BASE is defined,
smp_kicl_all_cpus may enable secondary cores and runs into secure_ram_addr(
_smp_pen), before code is relocated to secure ram.
So need relocation to secure ram before enable secondary cores.
