Add 'compatible = "pciclass,0604"' to the pcieport0 node in lemans.dtsi to allow the PCI subsystem to associate the DT node with the PCI-to-PCI bridge device. This is required for downstream DT nodes (such as M.2 connectors described as graph endpoints of the Root Port) to be matched to PCI devices.

…onnector 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.

This series enables the WCN6855 Bluetooth/WLAN module on the lemans EVK
via the PCIe M.2 Key E connector.
Patch 1 adds the PCI-to-PCI bridge compatible to the lemans pcieport0
Root Port in the SoC dtsi, required for downstream M.2 connector graph
endpoints to be matched to PCI devices.
Patch 2 describes the M.2 Key E connector on lemans-evk and links it
with PCIe RP0 and UART17 via graph ports/endpoints.
