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.
