Perform git mv & fix all failing DT and drivers in a single commit.
You might also update guarding defines, if you wish. Perform all other
changes in a separate commit.

This way git diff will actually tell what has happened, instead of us
seeing a series of add files, perform changes, remove files. It is
impossible to review your changes otherwise.
