[PATCH v5 6/9] dt-bindings: connector: m2: Add M.2 1620 LGA soldered down connector

[Manivannan Sadhasivam via B4 Relay]

From: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxxxxxxxx>

Lenovo Thinkpad T14s is found to have a soldered down version of M.2 1620
LGA connector. Though, there is no 1620 LGA form factor defined in the M.2
spec, it looks very similar to the M.2 Key E connector. So add the
"pcie-m2-1620-lga-connector" compatible with "pcie-m2-e-connector" fallback
to reuse the Key E binding.
