clk: tegra: Micro-optimize Tegra210 clock setup
sor_safe being the parent of the dpaux and dpaux1 clocks, it's not only natural, but also slightly more efficient, to initialize it before its children. This avoids orphaning the dpaux and dpaux1 clocks only to get them reparented when the sor_safe clock is registered.
