core: factorize cpu support
Create core/arch/arm/cpu/<cpu-name>.mk to store CPU generic configurations
settings. Update supported platforms to rely on the generic CPU support.
Platform shall still specify whether they support or not the NEON
extension.
Cortex-A53 and Cortex-A57 are all ARMv8.0 compliant. For ARMv8 core,
we will use ARMv8-A architecture minor version configuration files.
