clk: tegra: fix old-style declaration

With extra warnings enabled, gcc complains about a slightly odd
prototype:

drivers/clk/tegra/clk-dfll.c:1380:1: error: 'inline' is not at beginning of declaration [-Werror=old-style-declaration]
 1380 | static void inline dfll_debug_init(struct tegra_dfll *td) { }

Move the 'inline' keyword to the start of the line.
