Since 7e5a875fff7d ("Compile libfdt for barebox"), we now also have
libfdt for operating on flattened device trees out of the PBL.
Document this.

The preferred way of adding board support to barebox is to have devices
on non-enumerable buses probed from device tree.

+barebox provide both the Linux OpenFirmware ``of_*`` and the libfdt ``fdt_`` APIs
+for device tree parsing. The former makes porting the device tree specific
+bits from Linux device drivers very straight forward, while the latter can be
+used for very early (PBL) handling of flattened device trees, should this be

Additionally, barebox has support for programmatically fixing up device trees
it passes to the kernel, either directly via ``of_register_fixup`` or via device
