In order to align with new ESARC, we add new property fsl,asrc-format.
The fsl,asrc-format can replace the fsl,asrc-width, driver
can accept format from devicetree, don't need to convert it to
format through width.

Should warn 'format' over 'width', since it's preferable.

Should goto asrc_fail as we did prior to the change.

And some of lines are over 80 characters.

Let's try this:
		ret = of_property_read_u32(asrc_np, "fsl,asrc-format",
					   &priv->asrc_format);
		if (ret) {
			/* Fallback to old binding; translate to asrc_format */
			ret = of_property_read_u32(asrc_np, "fsl,asrc-width",
						   &width);
			if (ret) {
				dev_err(&pdev->dev,
					"failed to decide output format\n");
				goto asrc_fail;
			}

			if (width == 24)
				priv->asrc_format = SNDRV_PCM_FORMAT_S24_LE;
			else
				priv->asrc_format = SNDRV_PCM_FORMAT_S16_LE;
		}
