Remove selection of OLD_IRQ_AT91 when selecting dt boards. Select ATMEL_AIC_IRQ for sama5 SoCs (a kernel compiled for this SoC will always use ATMEL_AIC_IRQ driver). Select ATMEL_AIC_IRQ for at91rm9200 and at91sam9 SoCs only if OLD_IRQ_AT91 is not selected (which means we are compiling a pure DT kernel, without any legacy board support). Remove specific irq init code in all dt board files: this init procedure is automatically handled in of_irq_init which is called by the arm irq core code and is in charge of calling the appropriate aic init functions.
