Some DTBOs might use symbols from other DTBOs and require them to be
applied before them.
Sort them based on the __symbols__ and __fixups__ nodes, by creating a
dependency graph.

Use the logging module to log important information to various log
levels: info, debug, warning and error.
- Modify __str__ representations of classes DeviceTree and
InnerMergedDeviceTree for readability in debug logs
- Make parse_dt_files() return instead of yield so as to order all the
filename parsing at one go after the preceding log messages
Use the argparse module to specify script arguments cleanly. Also make
the corresponding change to merge_dtbs.sh to invoke this script with the
correct flags.

When debugging issues with the script, it helps to not have in the
script's output the fully qualified path names of the DTB and DTBO files
being merged as they are very lengthy. Retain only the relevant parts of
the filnames - the basenames for better readability.
