memory: emif: Load the correct custom config values from dt
of_get_property returns value in Big Endian format. Before using this value it should be converted to little endian using be32_to_cpup(). Custom configs of emif are read from dt using of_get_property, but these are not converted to litte endian format. Correcting the same here.
