commit 7d2c0c0516e63b71a3476d3b4b6d38406d237486

    PCI: Leave Apple Thunderbolt controllers on for s2idle or standby
    
    commit 4694ae373dc2114f9a82f6ae15737e65af0c6dea upstream.
    
    On Macbook 2013, resuming from suspend-to-idle or standby resulted in the
    external monitor no longer being detected, a stacktrace, and errors like
    this in dmesg:
    
      pcieport 0000:06:00.0: can't change power state from D3hot to D0 (config space inaccessible)
    
    The reason is that we know how to turn power to the Thunderbolt controller
    *off* via the SXIO/SXFP/SXLF methods, but we don't know how to turn power
    back on.  We have to rely on firmware to turn the power back on.
    
    When going to the "suspend-to-idle" or "standby" system sleep states,
    firmware is not involved either on the suspend side or the resume side, so
    we can't use SXIO/SXFP/SXLF to turn the power off.
    
    Skip SXIO/SXFP/SXLF when firmware isn't involved in suspend, e.g., when
    we're going to the "suspend-to-idle" or "standby" system sleep states.
