Heinrich Schuchardt ceec977ba1 rng: Provide a RNG based on the RISC-V Zkr ISA extension
The Zkr ISA extension (ratified Nov 2021) introduced the seed CSR. It
provides an interface to a physical entropy source.

A RNG driver based on the seed CSR is provided. It depends on
mseccfg.sseed being set in the SBI firmware.
