[POWERPC] Remove linux,device properties
The linux,device property isn't used anywhere within the kernel, and since it's a kernel pointer, it's a little useless for userspace. This change removes the code to create this property in of_device_register. Built for pmac32. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
