[v9,00/10] drm/hdcp: Pull HDCP auth/exchange/check into helpers

Message

Hi all,
This is v7 of the HDCP patches. The patches are authored by Sean Paul. 
I rebased and addressed the review comments in v6-v9.

Main change in v9 is renaming i915 priv data and moving the display type specific init to the drm helper instead of the driver.

Patches 1-4 focus on moving the common HDCP helpers to common DRM. 
This introduces a slight change in the original intel flow
as it splits the unique driver protocol from the generic implementation.

Patches 5-7 split the HDCP flow on the i915 driver to make use of the common DRM helpers.

Patches 8-10 implement HDCP on MSM driver.

Thanks,
-Mark Yacoub
