drm: Add some HDCP related #defines
In preparation for implementing HDCP in i915, add some HDCP related
register offsets and defines. The dpcd register offsets will go in
drm_dp_helper.h whereas the ddc offsets along with generic HDCP stuff
will get stuffed in drm_hdcp.h, which is new.
Changes in v2:
- drm_hdcp.h gets MIT license (Daniel)
Changes in v3:
- None
Changes in v4:
- None
Changes in v5:
