    soc/intel/skylake: Set FSP-S UPD PchHdaIDispCodecDisconnect to 1
    
    As per Audio PCH team recommendation the iDisplay Audio/SDIN2
    should be disabled to bypass InitializeDisplayAudio() function
    call. Display Audio Codec is HDA-Link Codec, which is not
    supported in I2S mode
    
    BUG=chrome-os-partner:61548
    BRANCH=none
    TEST=Tested to verify that InitializeDisplayAudio() does not
    gets called.
