[PATCH] b44-ssb: Fix the SSB dependency hell

[Michael Buesch <mb@bu3sch.de>]

This fixes the SSB dependency hell and introduces some
fake-options that only give some advice on what to select.

We live with these fake options only until menuconfig is able
to tell more about needed dependencies and how to resolve them.

I think this should be merged into the ssb branch of
wireless-dev, unless you plan to maintain a seperate branch
for b44-ssb. But I think merging it with the ssb core is
probably OK.
