Subject: [PATCH] ARM: at91/DT: add NAND + DMA property

Add the "atmel,nand-has-dma" property to NAND node for SoC that
can use the DMA to perform NAND accesses.
Use of this property was added in 1b7192658a08f70df0f290634fd7cd2ecb629fc9
(mtd: atmel_nand: add a new dt binding item for nand dma support).
