target/riscv: Add some comments for sstatus CSR in riscv_cpu_dump_state()

Browse source 
sstatus register dump is currently missing in riscv_cpu_dump_state().
As sstatus is a copy of mstatus, which is described in the priv spec,
it seems redundant to print the same information twice.

Add some comments for this to let people know this is intentional.
