Subject: Split the Cell BE support into generic and platform dependant parts. From: Geoff Levand Creates new config variables PPC_CELL_NATIVE and PPC_IBM_CELL_BLADE. The existing CONFIG_PPC_CELL is now used to denote the generic Cell processor support. PPC_CELL = make descends into platforms/cell PPC_CELL_NATIVE = add bare metal support PPC_IBM_CELL_BLADE = add blade device drivers, etc. Also renames spu_priv1.c to spu_priv1_mmio.c.
