For many drivers which will support rich endianness of Devices
need define DT properties by itself with the binding support.

Index Device DT properties needed
------------------------------------------
1 BE 'big-endian'
2 LE 'little-endian'
Please see the regmap binding for more detail information of
the endianness support.
