Just looking at this again now. So you're right in that the main
reason for moving these out of platform code and into the system-wide
platform data area is for the memcpy channels. However, I'd prefer to
keep the channel allocation enum fully contiguous rather than
splitting them out.

The channels are only exposed to the one external driver which
includes them, and that's the D40 driver.

How against this move are you?
