Hi,

this series add the support to load FIT image supplied devicetree overlays.

The overlay loading wasn't coupled to bootm due to the following
reasons:
 - Users can add their own overlay filter
 - By making use of the common overlay handling we can specifiy a
   different/separate FIT image which provides only overlays.
 - It should be possible to apply FIT image overlay to the barebox
   live-tree (not implemented yet).

Changes in v4:
- Link to v3: https://lore.barebox.org/20240703-v2024-05-0-topic-fit-overlay-v3-0-c1fd766fd31d@pengutronix.de
- resolve possible filename links to make caching more robust

Changes in v3:
- Link to v2: https://lore.barebox.org/barebox/20240613125818.30499-1-m.felsch@pengutronix.de/
- drop of.overlay.fitconfigpattern usage and make use of an match-fn
  instead
- fit_get_handle(): make use of strcmp
- open_fits: make it static
- fit_close(): use free unconditional

Changes in v2:
- Link to v1: https://lore.pengutronix.de/barebox/20240322164953.1772129-1-m.felsch@pengutronix.de/
- add caching to improve the overlay load time if the same FIT, which
  provides the overlays, provides the kernel, of, initrd.
