Changed logic for gathering dtb list to just use a wildcard for boards that we're interested in. Changed generate_chromebook_its.sh logic to just take in scattered dtb files. Compressed all input files that go into the .its Here are some comparisons: none: 37M lz4: 17M < chosen in this commit lzma: ~10M but boots 1 second slower Since it's compressed the .its now had to include external compatible properties, used `fdtget .dtb / compatible`.
