[PATCH v5 09/11] dt-bindings: connector: pcie-m2-e: Add vendor LGA connector compatible

[Loic Poulain <loic.poulain@oss.qualcomm.com>]

Some modules (e.g. the Qualcomm QCA2066/QCNFA765) expose the same M.2
Key E interface signals but are physically soldered as an LGA package
rather than plugged into a real M.2 Key E connector socket. Such designs
are not actual M.2 Key E connectors, so describe them with a dedicated
vendor-specific compatible while keeping "pcie-m2-e-connector" as a
fallback for the shared signal semantics.

Add "qcom,pcie-m2-1418-lga-connector" for the M.2 LGA 1418 found on
Arduino Ventuno Q (Monaco Monza).

Add "qcom,pcie-m2-1620-lga-connector" for the M.2 LGA 1620 found on
The Lenovo Thinkpad T14s.
