[PATCH] ASoC: Intel: kbl_rt5663_rt5514_max98927: Simplify clk_get() usage

[Christophe JAILLET]

If clk_get() returns -ENOENT, there is no need to defer the driver, -ENOENT
will be returned the same for each retries.
So, return the error code directly instead of -EPROBE_DEFER.

Remove this special case and use dev_err_probe() to simplify code. It will
also be less verbose if the clk is really deferred.

This is based on my understanding of clk_get().
Review with care.

Not sure the Fixes tag is needed. The patch does not fix anything.
If devm_clk_get() returns -ENOENT, it will just loop several time until
the framework gives up.
If it returns -EPROBE_DEFER, this case is already handled by the
"return ret;"

So this patch should be a no-op, just a clean-up.
