[POWERPC] MPIC: support more than 256 sources
Allow more than the default 256 MPIC sources. Allocates a new flag
(MPIC_LARGE_VECTORS) to be used by platform code when instantiating
the mpic.
I picked 11 bits worth right now since it would cover the number of
sources on any hardware I have seen. It can always be increased later
if needed.
