irqchip: atmel-aic: Add atmel AIC/AIC5 drivers
Add AIC (Advanced Interrupt Controller) and AIC5 (AIC5 is an evolution of
the AIC block) drivers.
Put common code in irq-atmel-aic-common.c/.h so that both driver can access
shared functions (this will ease maintenance).
These drivers are only compatible with dt enabled board and replace the
old implementation found in arch/arm/mach-at91/irq.c.
