[coreboot-gerrit] Change in ...coreboot[master]: fit: Add overlay support

[Julius Werner (Code Review)]

Hello Patrick Rudolph,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/32873

to look at the new patch set (#2).

Change subject: fit: Add overlay support
......................................................................

fit: Add overlay support

This patch adds support to boot FIT image configurations consisting of
a base device tree and one or more overlays. Since extracting the right
compatible string from overlay FDTs is problematic, we'll only support
this for FIT images that have the compatible string pulled out into the
config node.

This patch was adapted from depthcharge's http://crosreview.com/1555293
