2812: Add a software hash to Tock and connect it to TicKV r=bradjc a=alistair23 ### Pull Request Overview This PR adds a software SipHash to the Tock kernel, this includes a test case to ensure it's working. Then we connect the hash to TicKV to generate keys. SipHash was selected as it is quick while also providing resilience to DOS attacks from untrusted applications. This is compared to FNV which although quicker for short strings, is not resilient against arbitrarily long input. This applies on top of: #2804 Fixes: #2413 ### Testing Strategy OpenTitan unit tests. ### TODO or Help Wanted ### Documentation Updated - [X] Updated the relevant files in `/docs`, or no updates are required. ### Formatting - [X] Ran `make prepush`.

Pull Request Overview
This PR bumps the OpenTitan bitstream SHA and also adds support for the new CW310 board supported by OpenTitan.
The two designs are very similar, but the CW310 has the full amount of flash and also includes some missing components (such as the OTP).
