clk: tegra: Make tegra_clk_pll_params __ro_after_init

These structures are only passed to the functions tegra_clk_register_pll, tegra_clk_register_pll{e/u} or tegra_periph_clk_init during the init phase. These functions modify the structures only during the init phase and after that the structures are never modified. Therefore, make them __ro_after_init.
