[PATCH v3 6/6] arm64: dts: qcom: qcs8550-rb5gen2: clean up PCI function nodes

[Alex Elder <elder@riscstar.com>]

The Qualcomm RB5gen2 devicetree source file defines a node representing
a TC956x chip which contains a PCIe switch and an embedded endpoint that
implements two PCIe functions.

The devicetree nodes erroneously include a "pci" device_type property
for the two PCIe functions.  That property should only be used for a
PCI device "that implements a PCI bus".  Remove this property for the
two function nodes.

In addition, only PCI bridge nodes should be named "pci@" (or "pcie@").
PCI endpoint nodes are typically named based on the functionality they
implement (e.g., "ethernet@").  In this case, the role of these PCI
functions is not (yet) specified, and furthermore they will be used
with PCI endpoint buses.  Rename these to use "dev@", following the
convention used in of_pci_make_dev_node() for dynamically-created
devicetree nodes.

Finally, these nodes define #address-cells, #size-cells, and ranges
properties, which are not normally defined for PCIe endpoints.  Remove
these properties as well; they can be added back once they are actually
needed/used.
