        src/sys/arch/arm/arm32: bus_dma.c

Log Message:
if we have to bounce a buffer, clear our anything already setup in
the map before trying again.

riastradh@ noticed that a map had two types of mbuf types, and this
seems to avoid it as seen on eqos(4) on quartz64.

add a couple more event counts for bus dma events.

ok @skrll @raistradh @jmcneill

XXX: pullup-8 and pullup-9 probably.
