[ Upstream commit e52928e8d5c1c4837a0c6ec2068beea99defde8b ]
According to Documentation/devicetree/bindings/sound/simple-card.txt the 'simple-audio-card,dai-link' may be omitted when the card has only one DAI link, which is the case here.
Get rid of 'simple-audio-card,dai-link' in order to fix the following build warning with W=1:
arch/arm/boot/dts/imx6qdl-gw551x.dtsi:109.32-121.5: Warning (unit_address_vs_reg): /sound-digital/simple-audio-card,dai-link@0: node has a unit name, but no reg property
