[ Upstream commit 51bb08dd04a05035a64504faa47651d36b0f3125 ]
An object file cannot be built for both loadable module and built-in
use at the same time:
arm-linux-gnueabi-ld: drivers/net/ethernet/micrel/ks8851_common.o: in function `ks8851_probe_common':
ks8851_common.c:(.text+0xf80): undefined reference to `__this_module'
Change the ks8851_common code to be a standalone module instead,
and use Makefile logic to ensure this is built-in if at least one
of its two users is.
Fixes: 797047f875b5 ("net: ks8851: Implement Parallel bus operations")
