use a different get function that will also probe the driver, regardless

in device tree.
- modified the probe mechanism for the bus, when trying to get the bus
use a different get function that will also probe the driver, regardless
of present aliases in DT.
- added bindings for ds24xxx driver and eep_sandbox, because they are
referenced from devicetree now.
