The support for DaVinci DM* SoCs has been dropped. The code that used
to be relevant to dm644x is no longer needed. Remove it.

NAND flavors, like serial and parallel, have a lot in common and would
benefit to share code. Let's move raw (parallel) NAND specific code in a
raw/ subdirectory, to ease the addition of a core file in nand/ and the
introduction of a spi/ subdirectory specific to SPI NANDs.
