device_tree: Increase FDT_MAX_SIZE to 1 MiB

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

Hence increase the limit to 1 MiB, like on PPC.

For reference, the largest arm64 DTB created from the Linux sources is
ca. 75 KiB large (100 KiB when built with symbols/fixup support).
