Patch adds Support for DaVinci DM357. This has been tested on a DM357 EVM. It boots of a small page NAND on the EVM. This SOC is very similar to the DM644x. The DM357 EVM has 2 NANDs, one small page NAND and another large page NAND. But the device can only boot of the small page NAND. It does not have NOR support. This patch has been tested on the DM357 EVM.
