Subject: [PATCH 1/2] viafb: merge viafb_update_viafb_par in viafb_update_fix
viafb: merge viafb_update_viafb_par in viafb_update_fix
Shrink and merge viafb_update_viafb_par. This removes a lot of
duplicated data in viafb_par. Use the relevant data of fb_info instead.
On the way it removes an inconsistency in handling a second framebuffer which
only worked because viafbinfo1->par is modified to point to the same viafb_par
as viafbinfo->par.
Code cleanup only, no runtime change expected.
