b43: Workaround DMA quirks
Some mainboards/CPUs don't allow DMA masks bigger than a certain limit. Some VIA crap^h^h^h^hdevices have an upper limit of 0xFFFFFFFF. So in this case a 64-bit b43 device would always fail to acquire the mask. Implement a workaround to fallback to lower DMA mask, as we can always also support a lower mask.
