ARM: at91: fix rtc-at91sam9 irq issue due to sparse irq support
AT91_ID_SYS as virq is incorrect because of spare irq support which introduces NR_IRQS_LEGACY offset. It modifies rtc-at91sam9 driver in order to get irq from resources. Signed-off-by: Ludovic Desroches <ludovic.desroches@atmel.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
