[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. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
