[PATCH] device_tree: Increase FDT_MAX_SIZE to 128 KiB

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

It is not uncommon for a contemporary FDT to be larger than 64 KiB,
leading to failures loading the device tree from sysfs:

    qemu-system-aarch64: qemu_fdt_setprop: Couldn't set ...: FDT_ERR_NOSPACE

For reference, the largest arm64 DTB created from the Linux sources is
70 KiB large (93 KiB when built with symbols/fixup support).
