Christopher Braga c24090b2c5 disp: msm: dp: Avoid double authentication if first is still in progress
In scenarios where two streams become active in a short time period, HDCP
authentication may incorrectly be kicked off twice. This occurs due to the
HDCP state machine not indicating when authentication is already in
progress.

Update the dp_dispay HDCP state machine to only transfer to the
authenticating state once authentication has begun.
