Funny, since this is what I did 1st before I re-read the original commit
log in more detail. :)  Oh well.  Here is the alternate solution.  You
guys can pick whichever one you like best.  I compile tested this one
as well.

Thanks,
Paul.

Subject: [PATCH] avr32: fix build failures from mis-naming of atmel_nand.h

Commit bf4289cba02b8cf770ecd7959ca70839f0dd9d3c (linux-next)

    "ATMEL: fix nand ecc support"

indicated that it wanted to "Move platform data to a common
header include/linux/platform_data/atmel_nand.h" and the new
header even had re-include protectors with:

    #ifndef __ATMEL_NAND_H__

However, the file that was added was simply called atmel.h
and this caused avr32 defconfig to fail with:

  In file included from arch/avr32/boards/atstk1000/setup.c:22:
  arch/avr32/mach-at32ap/include/mach/board.h:10:44: error: linux/platform_data/atmel_nand.h: No such file or directory
  In file included from arch/avr32/boards/atstk1000/setup.c:22:
  arch/avr32/mach-at32ap/include/mach/board.h:121: warning: 'struct atmel_nand_data' declared inside parameter list
  arch/avr32/mach-at32ap/include/mach/board.h:121: warning: its scope is only this definition or declaration, which is probably not what you want
  make[2]: *** [arch/avr32/boards/atstk1000/setup.o] Error 1

It seems the scope of the file contents will expand beyond
just nand, so ignore the original intention, and fix up the
users who reference the bad name with the _nand suffix.
