[PATCH 02/17] staging: tidspbridge: remove cod_init() and cod_exit()

[Víctor Manuel Jáquez Leal <vjaquez@xxxxxxxxxx>]

The cod module has a cod_init() and a cod_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.
