[PATCH 0/5] RFC: Displayport Link Policy Maker Update

This patch set lays the initial groundwork for updating the Displayport link policy maker
in the i915 driver. These first 5 patches add modular functions that have been split out
from the larger, monolithic ones present in the driver. The purpose of this work is the
following:
1) Improve reliability and operation of the Displayport link policy maker
2) Modularize and compartmentalize functionality to enhance readability and reliability
3) Allow more fine-grain control over the operation of the link policy maker
4) Enable features of Displayport such as Multistream Transport and compliance testing

Note that these new functions are not yet integrated into the operational code path(s). The
original functions have been left in place, as is, to maintain operational status. Follow on
patch sets will integrate these functions into the policy maker.
