drm/amd/display: DP HDCP Compliance 1A-08/09 tests fail
[Why]
Current implementation of mod_hdcp_hdcp2_validate_ake_cert()
does not process HDCP status message
TA_HDCP2_MSG_AUTHENTICATION_STATUS__SIGNATURE_CERTIFICAT_ERROR.
As a result, when there is a signature certificate error,
mod_hdcp_hdcp2_validate_ake_cert would return the default status,
which is success.
[How]
For all messages other than TA_HDCP2_MSG_AUTHENTICATION_STATUS__SUCCESS
and TA_HDCP2_MSG_AUTHENTICATION_STATUS__RECEIVERID_REVOKED, return status
as failure.
