Inspired by "828e0b45 yueyao@ build device tree overlay partition
image", integrating the same feature into floral kernel. The difference
is all build-time generated *.dtbo are packed into dtbo.img instead of
packing only the dtbos specified by the dtboimg.cfg.
dtbo.img is built only when CONFIG_BUILD_ARM64_DT_OVERLAY is set.
