chao an a51ebeab4b arch/risc-v: decouple Per-CPU scratch with ARCH_USE_S_MODE
In some special chipsets, multiple CPUs may be bundled in one hardware
thread cluster, which results in hartid and cpuindex not being exactly
the same. The new option will decouple Scratch-based Per-CPU storage
with S-Mode to distinguish the real cpu index.
