It's a core for hashing, but you should easily be able to tease out
the project-dependent bits.

The only difference between the i2c code in the two projects is that
the _simple version accepts a range of i2c device addresses, and
reports which one was requested. (And I normalized the addresses to 7
bits; for some reason Bunnie used an 8-bit register and ignored low
bit, so the device configured as "0x1e" was actually at address 0x0f.)

core/novena is paired with core/i2c, similar to the way
core/coretest_hashes is paired with core/uart.

I should consolidate core/novena and core/i2c into something like
core/novena_i2c, since I've now got novena_i2c_simple and novena_eim.
