arch/risc-v/src/mpfs/mpfs_cache.c: Move l2zerodevice to use cache ways starting from 0

Browse Source 
If scratchpad is being used, the cache way 0, which is automatically
enabled at boot, needs to be re-configured as part of scratchpad memory
Otherwise there is a possibility of random memory corruption in the
scratchpad
area due to cache eviction from way 0.
