device-tree: Setup COMPATIBLE_MACHINE

Setup COMPATIBLE_MACHINE for the device-tree recipe so that it is only
available to machines that have provided sources/device-trees.

The COMPATIBLE_MACHINE is defined by overrides to match any machine
('.*') which sets the targeted override. This allows for easy reuse of
sources across similar machines.
