Mengdong Lin 5015920a17 ASoC: Vendor drivers get a link's runtime by snd_soc_get_pcm_runtime() 
Vendor drivers no longer access a DAI link's runtime by the link index
but by matching the link name via snd_soc_get_pcm_runtime(). We assume
each DAI link has a unique name.

This is preparation for changing runtimes from an array to a list later.

Vendor drivers changed:
sound/soc/fsl/fsl-asoc-card.c
sound/soc/fsl/imx-wm8962.c
sound/soc/pxa/mioa701_wm9713.c
sound/soc/samsung/bells.c
sound/soc/samsung/littlemill.c
sound/soc/samsung/odroidx2_max98090.c
sound/soc/samsung/snow.c
sound/soc/samsung/speyside.c
