Two (bad) reasons:
- The crc4 implementation here is pretty specific to the FSI
usage (only supporting 4-bit-sized chunks), to keep the math & lookup
table simple
- I'm lazy
So

Add some helpers for the crc checks for the slave configuration table.
This works 4-bits-at-a-time, using a simple table approach.
We will need this in the FSI core code, as well as any master
implementations that need to calculate CRCs in software.
