[PATCH 3/6] ARM: at91: introduce the core type choice to split ARMv4/5 and ARMv7 arch

[ludovic.desroches at atmel.com]

From: Ludovic Desroches <ludovic.desroches at atmel.com>

As we will introduce SAMA5, we need to distinguish the core architecture. It is
useless to show ARMv4/5 entries if we are configuring a kernel for SAMA5
devices.
