Subject: [RFC] Patches to disable messages during BMC reset

I went ahead and did some patches for this, since it was on my mind.

With these, if a reset is sent to the BMC, the driver will disable
messages to the BMC for a time, defaulting to 30 seconds.  Don't
modify message timing, since no messages are allowed, anyway.

If a firmware update command is sent to the BMC, then just reject
sysfs commands that query the BMC.  Modify message timing and
allow direct messages through the driver interface.

Hopefully this will work around the problem, and it's a good idea,
anyway.
