[POWERPC] MPIC MSI allocator To support MSI on MPIC we need a way to reserve and allocate hardware irq numbers, this patch implements an allocator for that purpose. New firmware platforms must define a "msi-available-ranges" property on their MPIC node for MSI to work. For U3/U4 we do a best-guess setup.
