[PATCH v2 0/3] FIT: parse and use the cmdline property of FIT images

[Thomas Bonnefille <thomas.bonnefille@bootlin.com>]

As of FIT v0.9, it is possible to pass cmdline parameters to the
bootloader via a special property in the fitimage.
This series adds support for this feature in Barebox.
It also adds some tests to avoid any regression on this feature.
As `cmdline` is a property in a configuration that isn't a reference to
an image, it needs to be whitelisted by fit_config_build_hash_nodes() to
not be hashed.
