====================
Clean up SFP register definitions

This two-part patch series cleans up the SFP register definitions by
1. converting them from hex to decimal, as all the definitions in the
   documents use decimal, this makes it easier to cross-reference.
2. moving the bit definitions for each register along side their
   register address definition
====================
