riscv: Kconfig: enable SCHED_MC kconfig

Browse Source 
RISC-V now builds the sched domain based on the simple possible map.

which also takes care of the NUMA and cores with LLC.

Multi-core scheduler support improves the CPU scheduler's decision
making when dealing with multi-core CPU chips at a cost of slightly
increased overhead in some places. If unsure say N here.
