[PATCH 09/11] staging: tidspbridge: Remove cfg_set_object()

[Ivan Gomez Castellanos <ivan.gomez@ti.com>]

As the services directory is going to be removed, the cfg_set_object
function has also to be removed.

Since the driver object handle is retrieved from the drv_data structure,
then the word "Registry" is replaced by "driver data" in the comments.
