The i.MX25 contains two AHB to IP bridges (AIPS), each of which has a set of control registers. Add the memory regions for the control registers to the Device Tree.

One thing I haven't seen the first time: The size should be the size of the while register space given to this device, not the position of the last register, so 0x4000 instead of 0x60 here.
