arm64: dts: qcom: lemans-evk: Describe the PCIe M.2 Key E connector

Browse source

The lemans EVK has the PCIe M.2 Mechanical Key E connector to connect
wireless connectivity cards over PCIe and UART interfaces. Hence,
describe the connector node and link it with the PCIe 0 Root Port and
UART17 nodes through graph port/endpoint.

The M.2 Key E connector is powered by a 3.3V fixed regulator
(vreg_wcn_3p3) which is sourced from the board's 12V DC input rail
(vreg_dcin_12v). Both regulators are always-on and are required by the
pcie-m2-e-connector binding.

Also add the serial1 = &uart17 alias, which is required for the
Bluetooth serdev device to be enumerated on the UART17 interface.
