clk: tegra: make tegra_clocks_apply_init_table() arch_initcall
tegra_clocks_apply_init_table() needs to be called after the udelay loop has been calibrated (see commit 441f199a37cfd66c5dd8dd45490bd3ea6971117d ("clk: tegra: defer application of init table") for why that is). On existing Tegra SoCs this was done by calling tegra_clocks_apply_init_table() from tegra_dt_init(). To make this also work on ARM64, we need to change this into an initcall. tegra_dt_init() is called from customize_machine which is an arch_initcall. Therefore this should also work on existing 32bit Tegra SoCs. Tested on Tegra20 (ventana), Tegra30 (beaverboard), Tegra124 (jetson TK1) and Tegra132.
