Add the zstd library from Linux kernel (only decompression support). There are minimal changes to build with U-Boot, otherwise the files are identical to Linux commit dc35da16 from March 2018, the files had not been touched since in kernel. Also SPDX lincese tags were added. Signed-off-by: Marek Behún <marek.behun@nic.cz>
