[ros-arm-bringup] 34487: - Force a 5 second wait before loading drivers, on ARM. - Context switching doesn't really work -- but we've been lucky since we're stuck on a priority 31 thread. - Instead of worrying about this later when the system will be fully operational, this forces us to expose these bugs, and to make sure everything works. - This will stress our context switching, waiting, unwaiting and scheduling code on ARM but once it all works well, after 5 seconds we'll be back on track.

Log:
- Force a 5 second wait before loading drivers, on ARM.
- Context switching doesn't really work -- but we've been lucky since we're
stuck on a priority 31 thread.
- Instead of worrying about this later when the system will be fully operational, this
forces us to expose these bugs, and to make sure everything works.
- This will stress our context switching, waiting, unwaiting and scheduling code on ARM
but once it all works well, after 5 seconds we'll be back on track.
