I guess the reservation of dma channel 4 for "cascade" is
PC or chipset specific and we don't have such a thing in the
CRIS (ETRAX100LX) chip and channel 4 clashes with external dma0.
Perhaps a better fix is to #ifdef on something else or remove
the cascade stuff entirely from this file, but I leave that
to those who know better.
Have no other arch been bitten by this?

Please apply to both 2.4 and 2.5.
