clk: tegra20: Use custom CCLK implementation
We're going to use the generic cpufreq-dt driver on Tegra20 and thus CCLK intermediate re-parenting will be performed by the clock driver. There is now special CCLK implementation that supports all CCLK quirks, this patch makes Tegra20 SoCs to use that implementation.
