[PATCH v2 3/3] PCI: qcom: Restrict port parsing only to pci child nodes

[Krishna Chaitanya Chundru <krishna.chundru@oss.qualcomm.com>]

The qcom_pcie_parse_ports() function currently iterates over all available
child nodes of the PCIe controller's device tree node. This can lead to
attempts to parse unrelated nodes like OPP nodes, resulting in unnecessary
errors or misconfiguration.

Restrict the parsing logic to only consider child nodes named "pcie" or
"pci", which are the expected node names for PCIe ports.
