Up until now all dp hdcp specific function derived the aux
from dig_port which gave the aux of the primary port but with
DPMST when a MST hub comes into picture the monitor becomes remote
and what we need is a corresponding aux which is also remote.
These set of patches aim to fix up just that.

--v2
-Do not pass drm_core struct to i915 function [Arun]
-Fix typo and correct commit message in 3rd patch [Arun]
-Provide justification for timeout adjustment [Arun]
