viafb: modetable conversion
This patch converts the modetables used in viafb to
- remove the strange thing that sync_end and blanking_end contained
the length and not the absolute value
- remove hundreds of useless defines
- use fb_videomode and not our own definition so modes defined in
the subsystem and received via EDID are compatible with ours
As the modes are now stored in a flat structure and no longer in a
tree like thing the lookup time was increased but as it is a rare
event anyway it shouldn't matter. Otherwise the behaviour should be
the same as before.
