[U-Boot] [PATCH] ARM: arm1176: Define arch_cpu_init() at the SoC level

[Marek Vasut <marex@denx.de>]

Dear Stephen Warren,

> Commit 86c6326 "ARM: arm1176: enable instruction cache in
> arch_cpu_init()" defined arch_cpu_init() in a file that is shared across
> all arm1176 SoCs. tnetv107x already implemented this function, which
> caused linking to break. Move the new conflicting arch_cpu_init() into
> arm1176/bcm2835/init.c so that it doesn't conflict; grep indicates this
> function is usually defined at the SoC-level, not the CPU-level, at least
> for ARM.
