[PATCH] bcm43xx: optimization of DMA bitfields
Convert the bitfields in the bcm43xx DMA code to properly
aligned u8 booleans. These flags are accessed in the DMA
hotpath, so it's a good idea to waste a few bytes of memory
for the sake of speed by not requiring masking (and probably
shifting) of the bitfields.
