[PATCH] disable VT on iSeries by default

From: Paul Mackerras <paulus@samba.org>

This patch from Julie DeWandel makes CONFIG_VT default to N on iSeries
machines which are using the iSeries virtual console driver viocons.c.  The
VT console and the viocons code can't coexist because they use the same tty
numbers, that is, viocons supplies /dev/tty1.  Without this patch the user
has to figure out somehow that s/he has to turn on CONFIG_EMBEDDED in order
to be able to turn off CONFIG_VT, which is really very non-obvious.
