[U-Boot] [PATCH 1/3] ARM: lib: Remove CONFIG_ARCH_CPU_INIT dependency

[Marek Vasut <marex@denx.de>]

> Create a weak-aliased arch_cpu_init, so that we can get rid of
> CONFIG_ARCH_CPU_INIT and always call arch_cpu_init.
> 
> This way we do not need to define CONFIG_ARCH_CPU_INIT in every board file,
> since arch_cpu_init() is supposed to handle common CPU level code.
