ide: mark hpt34x host driver as BROKEN

Alan Cox has noticed some time ago that hpt34x is broken
(http://lkml.org/lkml/2007/7/3/257):

"No the old driver doesn't even do that. It starts up. It spuriously
adjusts some non writable PCI BAR registers, prints a message about
resources being in use already then exits."
