Switch to use internal PLL for iMCLK 

Merge series from Hui Wang <hui.wang@canonical.com>:

Taking your advice and try to enable internal PLL to get a more
accurate sample rate. And I also changed the fsl-asoc-card.c to support
the nau8822 codec, now the sound quality is pretty good on my imx6sx
EVB.
