ce910686f8 clk: tegra: Make gr2d and gr3d clocks children of pll_c
By default these clocks are children of pll_m, but in downstream kernels
they are reparented to pll_c. While at it, decrease their frequencies to
300 MHz because the defaults aren't in the specified range.

gr2d can reportedly run at much higher frequencies, but 300 MHz works
and is a more conservative default.

0203d91247 clk: tegra: fix driver to match DT binding
enum tegra*_clk is intended to match the IDs listed in the Tegra clock
bindings. There are a few mismatches, which this patch fixes:

1) pll_s and cop were left out of the Tegra20 enum.

2) spdif_in and spdif_out were swapped relative to the Tegra30 binding.

3) i2cslow was misnamed as i2c_slow, and a duplicate i2cslow clock added
   to the Tegra30 enum.

b4c154a339 clk: tegra: local arrays should be static

clk-tegra30.c. Declare them static to avoid namespace polution.

required to avoid corruption.

22ca335f6d clk: tegra: fix wrong clock index between se to sata_cold
The index of se should be 127. And the previous clock index was 125. So
we need to set up the index for se to get the correct index between se
to sata_cold.
