[MTD] NAND: Support for 16-bit bus-width on AT91.
Add support for 16-bit NAND bus-width for the AT91 NAND driver. The 16-bit NAND is found on the Atmel AT91SAM9260-EK and AT91SAM9261-EK boards. Orignal Patch from Patrice Vilchez Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
