David Daney 751c9f6849 MIPS: Oceton: Update model detection code for new chips. 
Several newer chips were not covered, update the code to detect them.
This necessitates updating cvmx-mio-defs.h as well, because it has new
and required definitions.

* The defines below should be used with the OCTEON_IS_MODEL() macro
* to determine what model of chip the software is running on. Models
* ending in 'XX' match multiple models (families), while specific
* models match only that model. If a pass (revision) is specified,
* then only that revision will be matched. Care should be taken when
* checking for both specific models and families that the specific
* models are checked for first. While these defines are similar to
* the processor ID, they are not intended to be used by anything
* other that the OCTEON_IS_MODEL framework, and the values are
* subject to change at anytime without notice.
*
* NOTE: only the OCTEON_IS_MODEL() macro/function and the OCTEON_CN*
* macros should be used outside of this file. All other macros are
* for internal use only, and may change without notice.
