[PATCH 5/5] arm64: dts: qcom: qcs6490-thundercomm-minipc-g1iot: use dev for device nodes

[Alex Elder]

A recent change caused the embedded PCIe endpoints on TC9564 SoCs to
be treated by the devicetree code as PCI buses, which is incorrect.

The Thundercomm AI Mini PC G1 IoT defines a TC956x SoC, which includes
a PCIe switch with one upstream port and two downstream (external)
ports, plus a third downstream port.  The third port has an embedded
PCIe endpoint with two functions, each providing access to a 10 Gbps
capable Ethernet interface.

The devicetree nodes representing these functions were previously
named "pci@" but were renamed in the interest of consistency in
commit e806c63ba51a7 ("arm64: dts: qcom: Rename pci@ nodes to pcie@").

Unfortunately, of_node_is_pcie() causes nodes named "pcie@" to be
treated as PCI bridges, which PCI endpoints are not.  The previous
name "pci" matched such nodes as "default-flags" bus type, defined
in the of_busses[] array.

Rename the PCIe endpoint nodes "pci@" so they are not mistaken for
bridge nodes by the devicetree parsing code.  This restores the
previous behavior, and allows them to be used for PCI endpoint bus.
