MLK-18878 DTS: imx8mq: Change USB nodes compatible strings We enabled the DM for xhci-imx8m driver which uses compatible string "fsl, imx8mq-dwc3". But found a issue that u-boot will get four USB bus not two. The reason is the low level driver xhci-dwc3 also adds the DM support which uses compatible string "snps,dwc3". Thus, one USB node and its dwc3 subnode are both binded as independent USB bus. Since the xhci-imx8m driver uses xhci-dwc3 as low level driver, to fix the issue we add -u-boot.dtsi files to change the USB node compatible string to "simple-bus" and change dwc3 node compatibe string to "fsl, imx8mq-dwc3". Then xhci-dwc3 DM driver won't bind any node. Signed-off-by: Ye Li <ye.li@nxp.com> (cherry picked from commit 7542babca0c1303d469642c346cc927de3facf12)
