Subject: [PATCH v7 05/12] clk: tegra30: Use custom CCLK implementation

We're going to use the generic cpufreq-dt driver on Tegra30 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 Tegra30 SoCs to use that implementation.
