dt-bindings: phy: qmp-ufs: Fix PHY clocks

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.

This change obviously breaks the ABI, but it is inevitable since the
clock topology needs to be accurately described in the binding.
