qcom,sc8280xp-qmp-usb3-uni-phy.yaml
Migrate legacy bindings (described in qcom,msm8996-qmp-usb3-phy.yaml)
to qcom,sc8280xp-qmp-usb3-uni-phy.yaml. This removes a need to declare
the child PHY node or split resource regions.

The qcom,msm8996-qmp-usb3-phy.yaml defines bindings for several PHYs
which predate USB -> USB+DP migration. Now as sm8150 has been migrated,
drop the legacy bindings completely. No device trees use them anymore.
Newer USB+DP bindings should use combo bindings from the beginning.

(SM6115 & QCM2290)
'qcom,msm8996-qmp-usb3-phy.yaml' defines bindings for several PHYs
which predate USB -> USB+DP migration. Since SM6115 and QCM2290
nodes for USB QMP phy are being added to dtsi files by followup patches,
move these bindings instead to the newer style
'qcom,sc8280xp-qmp-usb3-uni-phy.yaml' file.
Since no device trees use these bindings presently, so we have no ABI breakages
with this patch.

The current QMP USB 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 USB 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 (e.g. does not include the per lane PCS
registers).
Note that PCS_USB region is also not described by the current bindings
despite being used by the driver and this has led to people increasing
the size of the PCS region in the devicetree so that it includes PCS_USB
registers even though other regions like TX and RX may lie in between.
Add a new binding for the QMP USB PHYs found on SC8280XP which further
bindings can be based on.
Note that this also fixes the SC8280XP "phy_phy" reset name.
Also 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. And, specifically, there is no support in
mainline for the multiport controller that uses these PHYs.

In preparation for adding new bindings for SC8280XP which further
bindings can be based on, rename the current bindings after MSM8996 and
add a reference to the SC8280XP bindings.
