Dynamically control the log verbosity with a module parameter.
This enables us to dynamically enable debugging messages (or disable
info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose.
This increases the module size by about 3k. But in practice it reduces the
module size for the user, because some distributions ship the b43 module
with CONFIG_B43_DEBUG set, which increases the module by about 15k.
So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG.
There is no reason to keep it in a production-release kernel.
So we have a net reduction in size by about 12k.
This patch also adds a printk of the wireless core revision, so people
don't have to enable SSB debugging to get the wireless core revision.

First probe for proprietary firmware and then probe for opensource firmware.
This way around it's a win-win situation.
1) If proprietary fw is available, it will work.
2) If opensource firmware is available, but no proprietary (Distros can only ship open fw)
it might work.
3) If both open and proprietary are available, it will work, because it selects
the proprietary. We currently don't prefer the open fw in this case, because it doesn't
work on all devices. It would introduce a regression otherwise.
The remaining FIXMEs in this patch are harmless, because they only matter on multiband
devices, which are not implemented yet anyway.
