[PATCH] soc: qcom: llcc: Update the SCT table for IPQ5424

[Kathiravan Thirumoorthy]

Update the IPQ5424 LLCC slice configuration table to match the intended
cache consumers on the SoC.

Assign slice IDs 1 and 5 to the PPE RX descriptor and RX fill use cases,
slice IDs 6 and 7 to the Wi-Fi radios connected over PCIe, and slice ID
2 to the CPU subsystem. Adjust the corresponding capacities, priorities,
and way masks for these consumers.

Rename the usecase IDs for slice IDs 1 and 2 because LLCC_CPUSS and
LLCC_VIDSC0 do not describe the actual users of those slices.
