[U-Boot] [PATCH v5 0/3] fit: Image node compression

This patch series adds compression support for non-kernel FIT image
nodes (e.g. FDTs). The first patch is a preparatory refactoring, the
second adds the compression support itself, and the third adds a new
feature to compatible string matching that allows it to be useful
with compressed FDTs.

Sandbox-tested with FIT images with and without compressed FDTs, with
and without overlays, in both compatible string matching and direct
config selection modes. Also expanded the test_fit pytest to include a
case with compressed kernel, FDT and ramdisk.

Julius Werner (3):
  common: Move bootm_decomp_image() to image.c (as image_decomp())
    - First version: v5
  fit: Support compression for non-kernel components (e.g. FDT)
    - Changes for v2:
      - Changed from only supporting compressed FDTs to supporting all
        non-kernel image node types.
    - Changes for v3:
      - Fixed up some debug output that was still written for v1.
      - Fixed a mistake with handling FIT_LOAD_OPTIONAL_NON_ZERO when
        'load' was 0 (i.e. unset).
      - Added compression test case to the test_fit pytest.
    - No changes for v4
    - No changes for v5
  fit: Support compat string property in configuration node
    - No changes for v2
    - No changes for v3
    - Changes for v4:
      - Added documentation for compatible string in config node.
      - Added example .its file for compressed FDT with compat string in
        config node.
    - No changes for v5
