video: fbdev: aty128fb: make some arrays static const

Browse source 
Don't populate some read-only arrays on the stack but instead
make them static const. Also makes the object code a little smaller.
Re-format one of the declarations. Add spaces between commas and make
PostDivSet unsigned int to fixup checkpatch warnings.
