The bulk of the code is moving functions from user_sdma.c and others into a new
file, pin_system.c.

Not sure a bunch of commits "move XZY to pin_system.c" would be very helpful.

To be fair, the patch was posted originally almost 6 weeks ago. In that time no
one has said anything so I don't think there are a bunch of people chomping at
the bit to review this. Any suggestions to make it easier for your review?
