RISC-V: add SBI based cpuinfo
SBI appeared to be especially useful to implement a generic console
driver. However, SBI v0.2 removes these services without substitute.
We might find other use for it later, but for now, add the bare minimum
of querying the version of the running SBI implementation.
The cpuinfo command is intentionally kept generic. It can later be
extended to support CONFIG_RISCV_M_MODE as well.
