NAND DaVinci: Update to ALE/CLE Mask values

All DaVinci SOC's use a CLE mask of 0x10 and an ALE mask of 0x8
except the DM646x. This was decided by the design team driving the design.
This patch updates the CLE and ALE values for DM646x.
Updated patches for DM646x will be sent shortly.
This applies to u-boot-nand-flash git
