    drm/i915/cmtg: Disable the CMTG
    
    The CMTG is a timing generator that runs in parallel with transcoders
    timing generators and can be used as a reference for synchronization.
    
    On PTL (display Xe3_LPD), we have observed that we are inheriting from
    GOP a display configuration with the CMTG enabled. Because our driver
    doesn't currently implement any CMTG sequences, the CMTG ends up still
    enabled after our driver takes over.
    
    We need to make sure that the CMTG is not enabled if we are not going to
    use it. For that, let's add a partial implementation in our driver that
    only cares about disabling the CMTG if it was found enabled during
    initial hardware readout. In the future, we can also implement sequences
    for enabling CMTG if that becomes a needed feature.
    
    For completeness, we do not only cover Xe3_LPD but also all previous
    display IPs that provide the CMTG.
    
    v2:
     - DG2 does not have the CMTG. Update HAS_CMTG() accordingly.
     - Update logic to force disabling of CMTG only for initial commit.
