[riscv] Add support for the seed CSR as an entropy source
The Zkr entropy source extension defines a potentially unprivileged
seed CSR that can be read to obtain 16 bits of entropy input, with a
mandated requirement that 256 entropy input bits read from the seed
CSR will contain at least 128 bits of min-entropy.
