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.

Clear all RAM during start 
Since SRAM has some data remanence even without power it seems good
hygien to clear all RAM when starting the device so as not to leak
potential sensitive data between device apps.
