Subject: [PATCH v5 11/14] ARM: mvebu: Set the start address of a CPU in a separate function

Setting the start (or boot) address of a CPU is no more used only
during SMP bring up, but it will also be used by the CPU idle
functions or later by the CPU hot plug ones.

This commit moves it in a separate function.
