commit 0de6db30ef79b391cedd749801a49c485d2daf4b upstream.
tegra_asoc_utils uses clk_get() to get the clock and clk_put() to free them explicitly.
This patch updates it to use device managed resource API devm_clk_get() so the clock will be automatically released and freed when the device is unbound and removes tegra_asoc_utils_fini() as its no longer needed.
