Subject: [PATCH V2 1/3] dt-bindings: interconnect: Add EPSS L3 compatible for QCS8300 SoC

Add Epoch Subsystem (EPSS) L3 interconnect provider binding for
QCS8300 SoC. As the EPSS hardware in QCS8300 and SA8775P are same,
added a family-level compatible for SA877P SoC. This shared fallback
compatible allows grouping of SoCs with similar hardware, reducing
the need to explicitly list each variant in the driver match table.
