Increase SPI com timeout for cold start and wake up There are use cases which cause the startup at Main to be longer than 300ms. In that case error reaction on RTE side would take place even if not needed. On the other hand having an longer timeout delays timeout detection and therefor the time till connection is reestablished => Added function to separate startup from common operation use case
