When verifying watchdog feature on NXP ls1046ardb board,
it doesn't work. Because in commit 7c8ffc5555cb("arm64: dts: layerscape:
remove big-endian for mmc nodes"), it intented 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, fsl,ls1046a-wdt allows big-endian property, so add it into
compatible property.

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