Qcom 8996 and later chips support prng v2 where we need to only
implement .read callback for hwrng.

Add a new table for v2 which supports this and get version required for
driver data.

Is this really a pseudo-RNG? If so it needs to be moved over to
the algif_rng interface.

Despite the register name (PRNG_ registers prefix) the IP is using FIPS
approved algorithm and we can claim that this is true hardware entropy
generator.

I don't think that we need to move to algif_rng.
