I introduced this since it was originally hardcoded to
us->US_BRGR = 33
for the AT91RM9200DK. The comment says "hardcode so no __divsi3".
I decdided that having a CFG_AT91C_BRGR_DIVISOR in your board specific
header file would be enough.
I had no time to test Peter's patch yet. But go ahead and apply it. If I
find problems I'll report them...
