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

[Fabio Estevam]

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.
