FROMLIST: PCI: qcom-ep: Add PCIe Endpoint support for Monaco

[ziyuezhang-123]

Add PCIe Endpoint support for Monaco (QCS8300) — dt-bindings, PHY configuration, driver fix, and DTS nodes.

Change 1: dt-bindings: phy: qcom,sc8280xp-qmp-pcie-phy: Add qcs8300 16 GT/s PHY
Document a dedicated "qcom,qcs8300-qmp-gen4x4-pcie-phy" compatible with "qcom,sa8775p-qmp-gen4x4-pcie-phy" as its fallback.

Change 2: dt-bindings: PCI: qcom-ep: Add QCS8300 compatible
Document the QCS8300 PCIe Endpoint compatible string and its fallback to SA8775P.

Change 3: phy: qcom: qmp-pcie: Add endpoint PHY configuration for QCS8300
Add 16 GT/s x4 Endpoint PHY configuration with required RX tuning parameters for Monaco.

Change 4: PCI: qcom-ep: Set initial interconnect bandwidth before enabling clocks
Move icc_set_bw() before clk_bulk_prepare_enable() to avoid clocks getting stuck in the off state.

Change 5: arm64: qcom: monaco: Fix pcie1_phy compatible to list qcs8300 first
List qcom,qcs8300-qmp-gen4x4-pcie-phy first with sa8775p as fallback.

Change 6: arm64: qcom: monaco: Add PCIe Endpoint nodes
Add pcie0_ep and pcie1_ep nodes for both Monaco PCIe controllers operating in Endpoint mode.
