[POWERPC] MPIC U3/U4 MSI backend MPIC U3/U4 MSI backend. Based on code from Segher, heavily hacked by me. This only deals with MSI on U3/U4 MPICs, aka. CPC 9x5. If we find a U3/U4 then we enable this backend, ie. take over the ppc_md MSI hooks. We might need more elaborate logic in future to decide which backend is enabled. We need our own irq_chip so that we can do MSI masking/unmasking on the device itself. We also need to mask explicitly on shutdown to make sure we don't get bitten by lazy-disable semantics.

[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.
