b43: Allow PIO mode to be selected at module load
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.
