ASoC: clarify that SND_SOC_IMX_SGTL5000 is the old driver 

Both SND_SOC_IMX_SGTL5000 and SND_SOC_FSL_ASOC_CARD implement the
fsl,imx-audio-sgtl5000 compatible string, which is confusing. It took a
little research to find out that the latter is much newer and it is
supposed to be the preferred choice since several years.

Add a clarification note to avoid wasting time for future readers.

Say Y if you want to add support for SoC audio on an i.MX board with
a sgtl5000 codec.
Note that this is an old driver. Consider enabling
SND_SOC_FSL_ASOC_CARD and SND_SOC_SGTL5000 to use the newer
driver.
