[PATCH 6/6] arm64: qcom: monaco: Add PCIe Endpoint nodes

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

Monaco has two PCIe controllers that can operate in Endpoint mode.
Describe the Endpoint nodes for both controllers, including their
register regions, clocks, interrupts, interconnects, IOMMU mappings,
resets, power domains, and PHY connections etc.
