ssb: Fix PCMCIA lowlevel register access
This fixes lowlevel register access for PCMCIA based devices. The patch also adds a temporary workaround for the device mac address. It simply adds generation of a random address. The real SPROM extraction will follow in another patch. The temporary workaround will be removed then, but for now it's OK. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.
