Those are only used when the driver is explicitly loaded with
use_msr=1.  The default is to use PCI config space/VSA.

In any case I have yet to see a CS5536 system whose BIOS sets the cable
detection bit.  If that's the problem I guess we could add a quirk flag
to override the (lack of) BIOS setting.
