[PATCH 5.15 019/124] ASoC: rk817: Use devm_clk_get() in rk817_platform_probe

[ Upstream commit 8ba08d3a367a70f707b7c5d53ad92b98b960ee88 ]

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.
