[RFC PATCH 3/5] hw/ppc: Have pSeries depends on libfdt (via host Kconfig FDT symbol)

[Philippe Mathieu-Daudé]

Since commit fea35ca4b8e ("ppc/spapr: Receive and store device
tree blob from SLOF") the pSeries machine depends on the libfdt
fdt_check_full() call, which is available in libfdt v1.4.7.

Add the corresponding Kconfig dependency.
