[ Upstream commit c2850c125d919efbb3a9ab46410d23912934f585 ]
[Why] When content type property is set to 1. We should enable hdcp2.2 and if we cant then stop. Currently the way it works in DC is that if we fail hdcp2, we will try hdcp1 after.
[How] Use link config to force disable hdcp1.4 when type1 is set.
