bcma: fix build error when build as module

Currently of_default_bus_match_table is not exported so we can only use this feature when bcma is build into the kernel. This patch removes support for child buses when bcma is build as a module as a temporary fix for a build problem introduces in this commit:

Thanks, manually applied to wireless-drivers-next.git. (Still patchwork.kernel.org has buggy utf-8 support, sigh.) I just added Reported-by and Fixes lines to the commit log.

I wrote a similar patch but I'll drop that as your has better comments :)
