Subject: [RFC PATCH] ASoC: simple-card: Use dai_id from node description

From: Daniel Baluta <daniel.baluta@....com>

We can specify DAI id using reg property. When dts
node has only 1 DAI simple-card always assumes that DAI id is 0.

But this is not correct in the case of SOF for example which adds DAIs
staticaly (See definition of snd_soc_dai_driver in sound/soc/sof/imx/imx8m.c)
