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).
