RADEON: initial pass at external TMDS support

- Based on Dave Airlie's initial work and the dvo support
in the intel driver.
- Only sil164 is supported at the moment.
- Once we get some testing and such, we ought to move the dvo
drivers out of the drivers so they can be shared among all drivers
- Doesn't seem to work on my card (r4xx ATOM) card ATM
- Legacy bios table programming sequence not implemented yet
