staging: tidspbridge: remove drv_init() and drv_exit()

Browse source 
The drv module has a drv_init() and a drv_exit() whose only purpose is
to keep a reference counting which is not used at all.

This patch removes these functions and the reference count variable.

There is no functional changes.
