Modify the Freescale Elo / Elo Plus DMA driver so that it can be
compiled as
a module.
The primary change is to stop treating the DMA controller as a bus,
and the
DMA channels as devices on the bus. This is because the Open
Firmware (OF)
kernel code does not allow busses to be removed, so although we can
call
of_platform_bus_probe() to probe the DMA channels, there is no
of_platform_bus_remove(). Therefore, the DMA channels must be
manually probed.

This patch is for the 2.6.28 kernel. This patch exposes a bug in
the dmatest
module, so my other patch "dmatest: properly handle duplicate DMA
channels"
should be applied if this patch is applied.
