[PATCH] fbcon: Add ability to save/restore graphics state

Add hooks to save and restore the graphics state.  These hooks are called in
fbcon_blank() when entering/leaving KD_GRAPHICS mode.  This is needed by
savagefb at least so it can cooperate with savage_dri and by cyblafb.

State save/restoration can be full or partial.
