dm: core: Allow device names to be freed automatically
Some devices have a name that is stored in allocated memory. At present
there is no mechanism to free this memory when the device is unbound.
Add a device flag to track whether a name is allocated and a function to
add the flag. Free the memory when the device is unbound.
