Subject: [PATCH] ASoC: codecs: Use devm_clk_get_enabled() helpers

From: ying zuxin <11154159@...o.com>

The devm_clk_get_enabled() helpers:
    - call devm_clk_get()
    - call clk_prepare_enable() and register what is needed in order to
     call clk_disable_unprepare() when needed, as a managed resource.

This simplifies the code and avoids the calls to clk_disable_unprepare().
