Subject: [PATCH] ARM: at91: enable new AIC driver even if the old one is selected

The new AIC driver is currently only selected when only DT board support
is enabled (and not when both DT and non-DT boards are supported), thus,
when booting a "DT + non-DT" kernel with a dtb, the irqchip is never
initialized/registered which then triggers a panic.
