Wifi (B43) broken on G4 PowerBooks with kernel v4.15

[Gabriel Paubert]

	Hi,

yesterday I recompiled the kernel on my late 2005 G4 PowerBook, and the
Wifi stopped working. After comparing the configuration is turns out
that a change to a Kconfig condition disabled SSB support which is
necessary for these chips.

The graph of configuration options is quite messy, and I'm not sure that
I fully understand it.

Nevertheless the following patch fixes the regression, but there might
be a better way to solve the problem.

If you pick up this trivial patch as is, you may add:
