clk: tegra: dfll: fix use of tune values

There was some confusion on the use of the tune values. They were
defined in 2 different structs, but only initialzed in one of them.
Remove most of the references in struct tegra_dfll_soc_data and adjust
the code accordingly. Only tune_high_min_millivolts is left, because
this can be adjusted using debugfs. Hence copy the initial value from
the cvb table at boot.
