[v7,1/2] dt-bindings: phy: qcom,qmp-usb: Drop legacy bindings and move to newer one (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.

Ok, let me add it in v8.

Thanks.
