Add support for detecting a vmlinux.bin appended dtb and overriding
the boot arguments to match the UHI interface.
Due to the PERCPU section being empty for !SMP, but still modifying
the current address by aligning it to the page size, do not define
it for !SMP builds to allow __appended_dtb to still point to
the actual end of the data.
