davinci dm6446evm NAND update
This updates the optional (non-default!) NAND support for the DaVinci DM6446 EVM: - include MTD partitioning, defaulting to what Linux uses - use a flash-based BBT, which among other things speeds bootup This matches code that's now queued for mainline Linux, and might even merge in an upcoming 2.6.30-rc; and the MTIDS are set up so that the U-Boot $mtdparts environment variable can be passed as-is on the kernel command line as a cmdlinepart override.
