We should read it as that 'big-endian' is a generic property defined by
generic bindings - bindings/regmap/regmap.txt, and we just reference the
bindings in fsl-imx-wdt.txt.

Taking mmc bindings as example, bindings/mmc/mmc.txt defines generic
bindings, while bindings/mmc/fsl-imx-esdhc.txt defines i.MX vendor
specific properties, which should ideally have vendor prefix.
