dtoc: Allow specifying the base directory for tests
The base directory of U-Boot, where the source is, it currently calculated
from the directory of the dtb_platdata.py script. If this is installed
elsewhere that will not work. Also it is inconvenient for tests.
Add a parameter to allow specifying this base directory.
To test this, pass a temporary directory with some files in it and check
that they are passed to scan_driver().
