[POWERPC] Fix new interrupt code (MPIC detection)
As the code comment already says, the Maple device-tree is incorrect here; make the Linux code detect the correct thing, too. Signed-off-by: Segher Boessenkool <segher@kernel.crashing.org> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
