[PATCH 01/16] dt-bindings: phy: qmp-ufs: Fix PHY clocks

Manivannan Sadhasivam

All QMP UFS PHYs except MSM8996 require 3 clocks:

* ref - 19.2MHz reference clock from RPMh
* ref_aux - Auxiliary reference clock from GCC
* qref - QREF clock from GCC or TCSR (since SM8550)

MSM8996 only requires 'ref' and 'qref' clocks. Hence, fix the binding to
reflect the actual clock topology.
