[MTD] [NAND] rename at91_nand -> atmel_nand: file names and Kconfig
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.
