phy: qcom-ufs-qmp-20nm: fix DIF-Z threshold 



In some cases link startup fails due to unexpected
termination caused by DIF-N to DIF-Z transition.
This patch will make PHY look only for DIF-N -> DIF-P
transition and not respond to DIF-N to DIF-Z transition.
Hence prevents a case where DIF-Z is identified as
DIF-P, which may result in unexpected LCC interpretation
and PHY switch to HS.
