Since commit 2eac58d (ARM: amba: make use of -1 IRQs warn), we're
able to detect the use of value -1 to indicate the lack of interrupt
line.
The RealView EB, when used with the 11MPCore tile, has a number of
devices without interrupts, and uses the value -1 to indicate this.
Change that value to 0 to conform to the new behaviour.
