    viafb: split global index up · dd73d686

    This is the first step to remove an artificial global index that was used
    in two ways:
    
    1. As a pseudo index in the mode table.  Pseudo as you had to search
       through the table to find the referenced entry.  This was replaced by
       using a pointer to the entry.
    
    2. As a shortcut to compare a combination of horizontal and vertical
       resolution at the same time.
    
       This was replaced by a "(hres<<16) | vres" which is good enough for
       now and the near future.  If vres or hres become greater than 2^16 this
       might indeed cause problems but this solution allows to split this
       indexing mess up without the requirement to do even more code changes.
    
    This is a big change that will allow more clean ups.  It should be a bit
    faster but that is probably not relevant for normal operation.  No
    regressions expected but as this is a relatively big step heavy testing is
    appreciated.
