ASoC: ES8389: convert to devm_clk_get_optional() to get clock 



When enabling ES8390 via ACPI description, es8389 would fail to
obtain a clock source, causing the driver to fail to initialize.
This was not an issue with older kernels, but since commit
abae8e57 ("clk: generalize devm_clk_get() a bit"),
devm_clk_get() would return an error pointer when a clock source
was not detected (instead of falling back to a static clock),
causing the driver to fail early.

Use devm_clk_get_optional() instead to return to the previous
behaviour, allowing the use of a static clock source.
