arm64: dts: qcom: add staging DT overlays for QPS615 enablement

[ayaan-anwar]

Add temporary, board‑specific Device Tree overlays to enable the QPS615 PCIe switch Ethernet ports (10GbE + 2.5GbE) without modifying existing base DTBs.

This PR introduces DTBO‑only “staging” overlays for:

• Lemans EVK IFP Mezz
• Monaco EVK IFP Mezz
• Rb3Gen2 (QCS6490)

The overlays wire up PCIe endpoints, WoL interrupts, PHY resets, regulators (where required), and MAC address provisioning. These overlays are intended as a short‑term workaround and will be removed once native upstream driver support lands.

QLI Mainline PR: qualcomm-linux/kernel-topics#909
Exception details: Until the QPS615 driver is upstreamed (third party ETA: end of 2026), an exception has been approved to include the driver and its devicetree entries as an out of tree DLKM only for QLI 2.0. (QLIJIRA-99, QLIJIRA-104).

why you need to add label ?

[ayaan-anwar]

Sure, will remove the label and reference pcieport* in the new .dtsi files.

same here ?

Ack

[shashim-quic]

I think you use node name directly and avoid adding labelling

Changes since the last review:

• Rebase to 6.18.y tip due to mezz ifp DT name change
• Update name of the new DTSI's to match the mezz ifp DT name change
• Define QPS615 layout of EEPROM for mac address retrieval

Feedback from OSTT is to maintain such addtiton as overlays. Let's sync up offline to get it done that way.
