brcm63xx: fix external IRQs 

External IRQs are currently broken, fix the BCM6345_EXT_IRQ driver.

Since the adoption of the new driver irq-bcm6345-ext, in Chaos Calmer,
external IRQs don't work. It seems there were some minor errors at the initial
development of the driver.

This patch fixes the ticket https://dev.openwrt.org/ticket/21613
