[PATCH 07/10] ASoC: AMD: Move clk enable from hw_params/free to startup/shutdown

[Vijendar Mukunda]

From: Akshu Agrawal <akshu.agra...@amd.com>

hw_param can be called multiple times and thus we can have
more clk enable. The clk may not get diabled due to refcounting.
startup/shutdown ensures single clk enable/disable call.
