[PATCH v2 3/4] ASoC: Intel: bytcht_es8316: Switch to use gpiod_get_optional()

[Andy Shevchenko]

First of all, replace indexed API by plain one since we have index 0.
Second, switch to optional variant and drop duplicated code.

[PATCH v2 4/4] ASoC: Intel: bytcht_es8316: Utilize dev_err_probe() to avoid log saturation

[Andy Shevchenko]

dev_err_probe() avoids printing into log when the deferred probe is invoked.
This is possible when clock provider is pending to appear.
