Subject: [PATCH] DTS: DMA: Fix DMA3 interrupts

From: Hongbo Zhang <hongbo.zhang@...escale.com>

MPIC registers for internal interrupts is non-continous in address, any
internal interrupt number greater than 159 should be added (16+208) to work.
16 is due to external interrupts as usual, 208 is due to the non-continous MPIC
register space.
Tested on T4240 rev2 with SRIO2 disabled.
