baytrail: allow function disable on TXE

Previously it was not known how to put the TXE pci device
    into D3Hot. It's been disseminated that this is not a requirement
    for disabling the TXE pci device in the function disable register.
    Therefore, allow this by returning 0 from place_device_in_d3hot().

BUG=chrome-os-partner:22871
    BRANCH=None
    TEST=Temporarily set TXE to be disabled. Noted FUNC_DIS was being
         set accordingly.
