Subject: sparc64: Oracle DAX driver depends on SPARC64

From: Guenter Roeck <linux@roeck-us.net>

commit 9c548bb5823dfcf7a16c6e65976d84d9581208c9 upstream.

sparc:allmodconfig fails to build as follows.

ERROR: "mdesc_release" [drivers/sbus/char/oradax.ko] undefined!
ERROR: "sun4v_hvapi_register" [drivers/sbus/char/oradax.ko] undefined!
ERROR: "mdesc_get_property" [drivers/sbus/char/oradax.ko] undefined!
ERROR: "mdesc_node_by_name" [drivers/sbus/char/oradax.ko] undefined!

ERROR: "sun4v_ccb_submit" [drivers/sbus/char/oradax.ko] undefined!
ERROR: "sun4v_ccb_kill" [drivers/sbus/char/oradax.ko] undefined!

The symbols are only available with SPARC64 builds, thus the driver
depends on it.
