Yes, we need to fix this. But I would not like to see this
"platform_data/atmel.h" renamed: I think that this file was designed to
collect several common platform data (ie: not just NAND related).

So maybe we should just rename the entry that exists in
mach-at32ap/include/mach/board.h
and remove all occurrences of platform_data/atmel_nand.h

No please.
