arm64: dts: add big-endian property back into watchdog node

Watchdog doesn't work on NXP ls1046ardb board because in commit
7c8ffc5555cb("arm64: dts: layerscape: remove big-endian for mmc nodes"),
it intended to remove the big-endian from mmc node, but the big-endian of
watchdog node is also removed by accident. So, add watchdog big-endian
property back.

In addition, add compatible string fsl,ls1046a-wdt, which allow big-endian
property.

Fixes: 7c8ffc5555cb ("arm64: dts: layerscape: remove big-endian for mmc nodes")
