[Intel-gfx] [PATCH v2 1/1] drm/i915/hdcp: Mandate zero seq_num_V at first RecvId msg

[Anshuman Gupta]

HDCP Repeater initializes seq_num_V to 0 at the beginning of
hdcp Session i.e. after AKE_init received, refer
HDCP 2.2 Spec HDMI PAGE 19, DP PAGE 20.

HDCP 2.2 Comp specs 1B-06 test verifies that whether DUT
considers failure of authentication if the repeater provides a
non-zero value in seq_num_V in the first,
RepeaterAuth_Send_ReceiverID_List message.

Make sure that HDCP repeater initializes seq_num_V to zero at
beginning of session i.e. after AKE_Init, fail the Auth if
there is non zero seq_num_V.

v2:
- Used existing hdcp2_encrypted flag instead of
  declaring new flag. [Ram]

As we dont have retry for topology authentication alone and it always
start with AKE_Init, we can rely on hdcp2_encrypted status for first
RepeaterAuth_Send_ReceiverID_List detection.

LGTM.
