[PATCH 2/2] dmaengine: bcm2835: Avoid splitting periods into very small chunks

The current cyclic DMA period splitting implementation can generate very small chunks at the end of each period. For example a 65536 byte period will be split into a 65532 byte chunk and a 4 byte chunk on the "lite" DMA channels. This increases pressure on the RAM controller as the DMA controller
