drm/amd/display: Don't try hdcp1.4 when content_type is set to type1
[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.
