Reset fdc during probe.
From: <dec@lazarus.nrtc.northrop.com>
Changes between EPSILON and RELEASE of FreeBSD have again caused
the kernel to not see my floppy disk drives. I don't know what happened,
'cause I don't see any changes to fd.c, but here is an old fix that
I have applied to the probe routine which will solve the problem (at
least for me). Since this is a rather brute-force solution - I understand
if you want to ignore it...
[Upgrading to pre-Beta FreeBSD caused this on my system. -AM]
