[ARM] CATS: Do not try and map bad PCI IRQ numbers
The cats_map_irq() function in the Simtec CATS support code is mapping IRQ 255 (invalid IRQ) into what is a supposedly valid interrupt numner which can cause problems with other devices then seeing an interrupt they cannot claim. If the IRQ number if >= 255, then return -1 as this is not something we can map. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
