kern/72703: Detection of Mitsumi FX4820T CDROM

I have a 4830T, which I believe had exhibited the same problems, on 
6.2-RELEASE now, and it's not giving me any trouble.  The others I have 
are in systems still running 5.4-RELEASE.

If I recall correctly, the problem only occurred if there were two 
drives on the channel.  I got in the habit of replacing the Mitsumi 
drives instead of just adding a DVD drive, to avoid the problem.  I 
haven't had many problems with these drives when they're used alone.

I haven't seen the atapicam issue with these drives in 5.4 or later.

I think this PR can be closed.  I submitted it mainly to advertise the 
workaround anyway.

Regards,

    Jason
