greybus: arche-platform: Rework platform/wd-line state transition logic

Browse source

This patch simplifies and improves the readability of the internal state
transition logic of arche platform driver state transition logic by:

1. Making a dedicated function to state-transition the platform code.
2. Condense the decision to swtich states down to a single switch
   statement instead of four separate if/else clauses.
