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.
