spapr.h: increase FDT_MAX_SIZE
Certain SMP topologies stress, e.g. 1 thread/core, 2048 cores and 1 socket, stress the current maximum size of the pSeries FDT: Calling ibm,client-architecture-support...qemu-system-ppc64: error creating device tree: (fdt_setprop(fdt, offset, "ibm,processor-segment-sizes", segs, sizeof(segs))): FDT_ERR_NOSPACE 2048 is the default NR_CPUS value for the pSeries kernel. It's expected that users will want QEMU to be able to handle this kind of configuration. Bumping FDT_MAX_SIZE to 2MB is enough for these setups to be created.
