fsl/mpic: Create and document the "single-cpu-affinity" device-tree flag
The Freescale MPIC (and perhaps others in the future) is incapable of routing non-IPI interrupts to more than once CPU at a time. Currently all of the Freescale boards msut pass the MPIC_SINGLE_DEST_CPU flag to mpic_alloc(), but that information should really be present in the device-tree. Older board code can't rely on the device-tree having the property set, but newer platforms won't need it manually specified in the code.
