Aaron Williams e7bc6eabd1 mips: octeon: Add misc cvmx-helper header files 
Import misc cvmx-helper header files from 2013 U-Boot. They will be used
by the later added drivers to support PCIe and networking on the MIPS
Octeon II / III platforms.

*
* Helper Functions for the Configuration Framework
*
* OCTEON_CN68XX introduces a flexible hw interface configuration
* scheme. To cope with this change and the requirements of
* configurability for other system resources, e.g., IPD/PIP pknd and
* PKO ports and queues, a configuration framework for the SDK is
* designed. It has two goals: first to recognize and establish the
* default configuration and, second, to allow the user to define key
* parameters in a high-level language.
*
* The helper functions query the QLM setup to help achieving the
* first goal.
*
* The second goal is accomplished by generating
* cvmx_helper_cfg_init() from a high-level lanaguage.
