AP_HAL_Linux: use pthread's barrier instead of polling
...
Use pthread's barrier so we don't keep waking up threads with possibly
higher priority during initialization phase.
This also synchronizes all of them to a single point. With the previous
approach it was possible (but unlikely) that a thread hadn't reach the
synchronization point when main thread signalize "system initialized".

AP_HAL_Linux: add name to SPI device table
