[PATCH] ide support for VIA 8237a southbridge

[Diego Calleja <diegocg@gmail.com>]

Alan Cox added (622b20fcb8b42aa4c3c87c0a036f2ad0927b64bc) some PCI IDs 
for some VIA devices, including the 8237a. The driver, however, has not
been changed to support the 8237a, and someone reported it through
bugzilla (http://bugzilla.kernel.org/show_bug.cgi?id=6925)

So I'm taking the one-liner from:
http://forums.viaarena.com/messageview.aspx?catid=28&threadid=72836&enterthread=y
and submitting it. Please merge it if appropiate.
