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.
