drm/i915/hdcp: Disable the QSES check for HDCP 1.4 over MST
The HDCP 1.4 spec does not require the QUERY_STREAM_ENCRYPTION_STATUS
check, it was always a nice-to-have. After deploying this across various
devices, we've determined that some MST bridge chips do not properly
support this call for HDCP 1.4 (namely Synaptics and Realtek).
I had considered creating a quirk for this, but I think it's more
prudent to just disable the check entirely since I don't have an idea
how widespread support is.
