[PATCH 2/8] rename at91_nand -> atmel_nand: file names and Kconfig

[Haavard Skinnemoen]

The AT91 NAND driver needs just a few tiny modifications to work on
AVR32 as well. Rename it atmel_nand to reflect this.

Also move the ECC register definitions into drivers/mtd/nand since they
are only useful to the atmel_nand driver, and get rid of the useless
filename at the top of each file.
