Add support for overlays from boot partition.

Adds capability to load DT overlays from the boot partition. These files
are indicated in the overlays.txt conffile (also located in the boot
partition). If an overlay fails, fallback to the default device tree.

Note: Debian doesn't currently generate symbols for the device trees so
you can't use the phandles and overlay concept of target. You must use
target-path (for example target=<&i2c2> must be
target-path="/i2c@30a30000").
