[ARM] TI DaVinci support, hopefully final

Add support for the following DaVinci boards:
- DV_EVM
- SCHMOOGIE
- SONATA

Changes:

- Split into separate board directories
- Removed changes to MTD_DEBUG (or whatever it's called)
- New CONFIG_CMD party line followed
- Some cosmetic fixes, cleanup etc.
- Patches against the latest U-Boot tree as of now.
- Fixed CONFIG_CMD_NET in net files.
- Fixed CONFIG_CMD_EEPROM for schmoogie.
- Made sure it compiles and works (forceenv() link problem) on SCHMOOGIE and
   DV_EVM. Can't check if it works on SONATA, don't have a board any more,
   but it at least compiles.

Here is an excerpt from session log on SCHMOOGIE...
