[PATCH 6/8] dmaengine: bcm2835: limit max length based on channel type

From: Martin Sperl The bcm2835 dma system has 2 basic types of dma-channels: * "normal" channels * "light" channels Lite channels are limited in several aspects: * internal data-structure is 128 bit (not 256) * does not support BCM2835_DMA_TDMODE (2D) * DMA length
