[PATCH] add raw driver Kconfig entry for s390

[Olaf Hering <olh@suse.de>]

From: Ihno Krumreich <ihno@suse.de>

The raw module is not enabled on s390/s390x
During SLES9 and SLES10 development IBM filed bugs about the missing raw
driver. Avoid that for SLES11 by adding it to the other char driver
entries.
