b43: Allow PIO mode to be selected at module load
commit b02914af4d7020828ce921a572589dd793517c09 upstream.
If userencounter the "Fatal DMA Problem" with a BCM43XX device, and
still wish to use b43 as the driver, their only option is to rebuild
the kernel with CONFIG_B43_FORCE_PIO. This patch removes this option and
allows PIO mode to be selected with a load-time parameter for the module.
Note that the configuration variable CONFIG_B43_PIO is also removed.
Once the DMA problem with the BCM4312 devices is solved, this patch will
likely be reverted.
