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.

dt-bindings: phy: migrate QMP UFS PHY bindings to qcom,sc8280xp-qmp-ufs-phy.yaml

Migrate legacy bindings (described in qcom,msm8996-qmp-ufs-phy.yaml)
to qcom,sc8280xp-qmp-ufs-phy.yaml. This removes a need to declare
the child PHY node or split resource regions.

# 7741f31a 24-Oct-2022 Johan Hovold <johan+linaro@kernel.org>

dt-bindings: phy: qcom,qmp-ufs: fix sc8280xp binding

The current QMP UFS PHY bindings are based on the original MSM8996 PCIe
PHY binding which provided multiple PHYs per IP block and these in turn
were described by child nodes.

The QMP UFS PHY block only provide a single PHY and the remnant child
node does not really reflect the hardware.

The original MSM8996 binding also ended up describing the individual
register blocks as belonging to either the wrapper node or the PHY child
nodes.

This is an unnecessary level of detail which has lead to problems when
later IP blocks using different register layouts have been forced to fit
the original mould rather than updating the binding. The bindings are
arguable also incomplete as they only the describe register blocks used
by the current Linux drivers.

Add a new binding for the UFS QMP PHYs found on SC8280XP which further
bindings can be based on.

Note that the current binding is simply removed instead of being
deprecated as it was only recently merged and support for SC8280XP is
still under development.
