dmaengine: fix balance of privatecnt inc/dec operations
This patch increments privatecnt value and set DMA_PRIVATE in device caps in dma_request_slave_channel() function. This is needed to keep privatecnt increment/decrement balance. As function dma_release_channel() decrements privatecnt counter, we need to increment it when channel is requested. Otherwise privatecnt drops into negatives after few dma_release_channel() calls.
