viafb: split global index up
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.
