video: tegra: host: adding throughput hint in 3dfs
adding support for using a throughput hint given by the tegra-gfx misc device in the 3d scaling code. If throughput hint usage is enabled and the latest throughput hint is recent enough (less than 1 second old), the throughput hint is used to control 3d frequency scaling. Otherwise the existing idle time percentage estimate is used.
