Log message:
em: Improve access logic for software flag
Some em chips have a semaphore ("software flag") to synchronize access
to certain registers between OS and firmware (ME/AMT).
Make the logic to get the flag match the logic in freebsd. This includes
higher timeouts and waiting for a previous unlock to complete before
trying a lock again.
