So far, zstd use was only possible from squashfs and ubifs.
Give it an update and add the necessary hooks to have it usable
everywhere where LZO and friends can be used. zstd would've
been a good default for barebox proper compression, but unfortunately,
the decompressor going into the PBL would be quite big:
lz4 lzo gzip xz zstd uncompressed
thumb2 barebox proper 671K 614K 544K 456K 531K 1022K
thumb2 barebox PBL 10K 10K 18K 17K 41K 9K
RIoTboard FDT 12K 11K 9K 7K 8K 39K
total thumb2 image 693K 635K 571K 480K 580K 974K
So, don't touch the defaults for now.

Ahmad Fatoum (5):
lib: zstd: adopt Linux directory structure
lib: zstd: sync with Linux
decompressor: define macros for non-PBL case as well
ARM: cpu: uncompress: increase early malloc pool to 256K
lib: uncompress: add general zstd support
