Subject: [PATCH 03/15] serial: bfin_5xx: fix building as module when early
	printk is enabled

From: Mike Frysinger <vapier@...too.org>

Since early printk only makes sense/works when the serial driver is built
into the kernel, disable the option for this driver when it is going to be
built as a module.  Otherwise we get build failures due to the ifdef
handling.
