    Don't show "standby timeout" setting for SSD drives
    
    Some SSD drives (erroneously?) has support for the standby timeout
    timer (hdparm -S) even though it doesn't make much sense as is
    intended for spinning down drives.
    
    So disable it for now. If it turns out that this is actually used for
    something in SSDs we can bring it back...
