[U-Boot] [PATCH] atmel_df_pow2: standalone to convert dataflashes to pow2

[Andrzej Wolski <awolski@poczta.fm>]

Page size is not always 1056/1024 bytes, it is depended on total memory 
size.

DafaFlash documentation says that "The device must be power cycled after 
the completion of the program cycle to set the power of 2 page size", so 
it would be good to print that information at the end of programming.
