radeon_ms: radeon modesetting first commit.

This should work on all radeon but there is still many things todo:
    - add crtc2
    - tmds
    - lvds
    - add bios data table so we don't need to hardcode dac/crtc infos
    - separate clock control to make power saving easier & cleaner
    - tiling (warning tiling shouldn't be enable in double scan or interlace)
    - surface reg manager (this goes along with tiling)
    - suspend/resume hook
    - avivo & r500 family support
    - atom bios support (for posting card mostly)
    - finish superioctl skeleton
    - what else ? :)
