Add check to remove HDCP2 compatibility from BMG as it does not
have GSC which ends up causing warning when we try to get reference
of GSC FW.

Fixes: 89d030804831 ("drm/xe/hdcp: Fix condition for hdcp gsc cs requirement")
Fixes: 883631771038 ("drm/i915/mtl: Add HDCP GSC interface")

The issue is without this IP_VER used below ends up throwing an error

Why do you say BMG doesn't have GSC?  I don't see anything in the bspec
indicating it wouldn't have it.

If you're missing the GSC firmware, then we'll disable the engine, but
that's true on any platform.

We are missing the GSC firmware here since the decision was taken not to code in GSC for this
Platform
Daniele can provide more information here
