From: Thierry Reding <treding@xxxxxxxxxx>
There is no reason why Tegra114 cannot use the same generic code to set
up the oscillator, clk_m and pll_ref clocks. The only effective change
that this causes is that the CLK_SET_PARENT_RATE flag is dropped, but
since these clocks are all fixed it is not needed anyway.
