From: Manivannan Sadhasivam <manivannan.sadhasivam@oss.qualcomm.com>

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 M connector. So add the
"pcie-m2-1620-lga-connector" compatible with "pcie-m2-e-connector" fallback
to reuse the Key M binding.
