arm64: dts: qcom: x1e78100-lenovo-thinkpad-t14s: Describe PCIe M.2 1620 LGA connector

Browse Source 
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 by supporting both
WiFi and BT interfaces.

Hence, add the M.2 1620 LGA connector node with fallback to Key E.
