misc: tegra-throughput: adding throughput dev node
Creates a miscdev at /dev/tegra-throughput which gl will use to set a
target frame rate. In addition it receives notifications from dc on
flip events. On each notification the percentage ratio of the actual
frame time to the target frame time is calculated. In subsequent
changes this ratio will be reported to other modules as a throughput
hint.
