Subject: [PATCH 11/15] ARM: dts: ls1021a: add fsl,ls1021a-wdt for watchdog
 node

Add compatible string fsl,ls1021a-wdt for watchdog node and failback to
fsl,imx27-wdt. And remove undocument property clock-names.

Fix below CHECK_DTB warning:
arch/arm/boot/dts/nxp/ls/ls1021a-moxa-uc-8410a.dtb: watchdog@...0000 (fsl,imx21-wdt): big-endian: False schema does not allow True
