[POWERPC] Make OF irq map code detect more error cases
Device-tree bugs on js20 with some versions of SLOF were causing the
interrupt for IDE to not be parsed correctly and fail to boot. This
patch adds a bit more sanity checking to the parser to detect some of
those errors and fail instead of returning bogus information. The
powerpc PCI code can then trigger a fallback that works on those
machines.
