This fix has been taken into clk-next for 3.11. tegra_clocks_init() is
missing in the clock tree so the patch below is what actually got
merged.

    clk: tegra: provide tegra_periph_reset_assert alternative
    
    We have some tegra device drivers that are written to be platform
    independent but still use the tegra specific tegra_periph_reset_assert
    function. In order to build and link them without errors,
    this provides a static inline version of these functions that
    does nothing when Tegra support is disabled.
