Update the IPQ5424 LLCC slice configuration table to give the PPE
and Wi-Fi datapaths dedicated slices.

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.

Having the dedicated slice configuration for each of these use cases helps
to improve the networking throughput by more than 1 Gbps.

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.
This reiterates the diff, but doesn't mention the actual reason for this
change (updated recommendations from the hardware team)

These slice assignments are based on recommendations from our performance team, following throughput measurements on IPQ5424 — not from a hardware team. Please let me know if I'm missing something here.
