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

This reverts commit 65d1cce7.

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 65d1cce7 ("ASoC: stm32: properly get clk from the
provider") until this gets sorted out.
