pipeline: raspberrypi: Add an error state

Add an error state used internally in the Raspberry Pi pipeline handler.
Currently this state is never set, but will be in a subsequent commit when a
device timeout has been signalled.

Add a isRunning() helper to identify if the state machine is in a stopped/error
state.
