For Freescale 8xxx devices that use an MPIC, the interrupt numbers in the
device tree must be 16 greater than the values documented in the reference
manual. In these chips, the MPIC is wired to use the first 16 numbers for
external interrupts, but the documentation numbers internal interrupts from 0.
In the MPC8610 HPCD device tree, the interrupt properties for the DMA channels
for DMA2 were not the adjusted values. This patch fixes that.

I have no idea how this was missed for so long, but this patch is a
must-fix for 2.6.27.
(changes for v2: improve changelog text)
