ppc44x: fix build of crypto4xx_core.c

crypto4xx_probe() is in the __init section and referenced by code form
other sections, which causes a build error. Backport a patch from
mainline kernel to fix this.

+Subject: [PATCH] crypto: amcc - remove incorrect __init/__exit markups
+
+Even if bus is not hot-pluggable, the devices can be bound and unbound
+from the driver via sysfs, so we should not be using __init/__exit
+annotations on probe() and remove() methods. The only exception is
+drivers registered with platform_driver_probe() which specifically
+disables sysfs bind/unbind attributes.
