Furthermore, this patch has the effect of only applying blen and
tchthr when voltage is present.

If this is a 224 device, but the platform data does not specify
voltage (say, we are ok with the existing value loaded from NVRAM),
then we won't apply blen and tchthr either.

As Benson noted in patch 5, what about the device that is neither 224
nor 224E ? burst length
and  threshold will no longer be applied.
