rS359672: riscv: Make sure local hart's icache is synced in pmap_sync_icache

Summary

The only way to flush the local hart's icache is with a FENCE.I (or an
equivalent SBI call); a normal FENCE is insufficient and, for the
single-hart case, unnecessary.

I broke this in rS339367 when I switched to using sbi_remove_fence_i as I had cleared the current CPU from the mask before passing that mask to SBI.
