Subject: b43: Allow switch to PIO without rebuilding kernel

For b43, switching between DMA and PIO mode requires rebuilding the
kernel. This situation is unfortunate as there are fatal DMA errors
with the BCM4312 on some Netbook computers, and those units will only
work with PIO mode.

This patch enables the usage of PIO mode with a module-load parameter.

It's rather an enhancement that should be merged in the upstream.
The golden rule still applies: the upstream first.

Care to send your patch to the subsystem ML / maintainer?
