libpayload/keyboard: Turn init sequence into a state machine

We'll process the init sequence as part of the polling loop. This
should have several advantages:

* It eases error handling, i.e. we can return to an earlier state.
* We don't have to stall initialization when a keyboard takes a
  little longer.
* Generally, these keyboards can be hot-plugged (albeit not by
  design).
