fw: Add support for blake2s MMIO 
In firmware we store the address to firmware blake2s() function at
TK1_MMIO_TK1_BLAKE2S so app can use this firmware function sort of
like a system call but without context switch.

fw: Introduce an explicit state machine - changes protocol! 
We introduce an explicit state machine (see README).

With the new states we:

- combine setting size and USS to a single command.
- start the device app immediatiely when having receceived the last
  data chunk and returning the digest.
- Loop forever and wait for the stick to be removed if we end up in
  unknown state.
