[PATCH RFC 4/4] boot/fit: print all configuration node compatibles

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

Fit conf node may have a compatible property[1] which stores the
compatible of the first blob in the fdt property of the node. This can
be used to automatically select the proper conf node based on the
compatible from the running U-Boot (matching the former's compatible
with the latter)[2].

This brings the ability to mkimage/dumpimage to print the compatibles of
the configuration node(s). U-Boot CLI commands such as iminfo also see
this addition to their output.
