Audio Client Interface (CIF) is a proprietary interface employed to route audio samples through Audio Hub (AHUB) components by inter connecting the various modules.
This patch exports an inline function tegra_set_cif() which can be used, for now, to program CIF on Tegra210 and later Tegra generations. Later it can be extended to include helpers for legacy chips as well.
