ARM: at91: sparse irq support

Enable sparse irq support for multisoc image. It involves to add the NR_IRQS_LEGACY offset to static SoC irq number definitions since NR_IRQS_LEGACY irq descs are allocated before AIC requests irq descs allocation. Move NR_AIC_IRQS macro to a more appropiate place with the purpose to remove mach/irqs.h later.
