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.
