Ramalingam C 08f68752ce drm/i915: HDCP state handling in ddi_update_pipe
The downgrade of the fullmodeset into fastset
intel_encoder->update_pipe, in possible scenario, skips the En/Dis-able
DDI. Hence breaks the HDCP state change handling.

We also don't have any hdcp tests in CI, because the shard runs don't
have hdcp capable outputs :-/

So this change fixs it by handling the HDCP state change request at
intel_encoder->update_pipe too along with enable and disable of the DDI.

Fixes: d19f958db2 ("drm/i915: Enable fastset for non-boot modesets.")
