Subject: [PATCH] ASoC: rk817: Use devm_clk_get() in rk817_platform_probe

We need to call clk_put() to undo clk_get() in the error path.
Use devm_clk_get() to obtain a reference to the clock, It has
the benefit that clk_put() is no longer required.

Fixes: 0d6a04da9b25 ("ASoC: Add Rockchip rk817 audio CODEC support")
