ASoC: stm32: do not request a new clock consummer reference

ASoC: stm32: do not request a new clock consummer reference

This reverts commit 2194e4df702c20f048ced5d68ffed3605fac0f13.

There is problem with clk_hw_get_hw(). Using it pins the clock provider to
itself, making it impossible to remove the module.

Revert commit 2194e4df702c ("ASoC: stm32: properly get clk from the
provider") until this gets sorted out.
