arm64: dts: qcom: qcs8300: Add EPSS l3 interconnect provider node and CPUCP OPP tables to scale DDR/L3

Add Epoch Subsystem (EPSS) L3 interconnect provider node and OPP tables
required to scale DDR and L3 per freq-domain on QCS8300 platform.
As QCS8300 and SA8775P SoCs have same EPSS hardware, added SA8775P
compatible as fallback for QCS8300 EPSS device node.
