[alsa-devel][PATCH 3/4] ASoC: wm8960: use pr_debug instead of pr_err

[Zidan Wang <b50113@freescale.com>]

In machine driver, we should find a appropriate sysclk for codec driver,
and will use codec set_dai_pll to judge if pll can generate such sysclk.
When sample rate changed, we should look for a useful bclk, lrclk division
ratio, and will try set_dai_pll for several times. So use pr_debug so that
don't generate much error logs.
