[PATCH 03/17] staging: tidspbridge: remove proc_init() and proc_exit()

[VÃctor Manuel JÃquez Leal]

The proc module has a proc_init() and a proc_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.
