[PATCH] arm/smp: Make boot_secondary() static

[Geert Uytterhoeven]

From: Geert Uytterhoeven <geert+renesas@xxxxxxxxxxxxxx>

After becoming a mandatory function, boot_secondary() is no longer used
outside arch/arm/kernel/smp.c. Hence make it static.
The code is reshuffled a bit to avoid a forward declaration.
