ASoC: da7219: do not request a new clock consummer reference 
This reverts commit 12f8127fe9.

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 12f8127fe9 ("ASoC: da7219: properly get clk from the
provider") until this gets sorted out.
