[Why]
We don't support HDCP for pre RAVEN asics
[How]
Check if we are RAVEN+. Use this to attach the content_protection
property, this way usermode can't try to enable HDCP on pre DCN asics.
Also we need to update the module on hpd so guard it aswell

This only introduces the ability to authenticate and encrypt the link. These

This reverts commit e01f2d41895102d824c6b8f5e011dd5e286d5e8b.

Leave VG10/12 workaround as some older shipped cards do not have the
VBIOS fix in place, and the kernel workaround is required in those
situations
