dma: shdma: transfer based runtime PM Currently the shdma dmaengine driver uses runtime PM to save power, when no channel on the specific controller is requested by a user. This patch switches the driver to count individual DMA transfers. That way the controller can be powered down between transfers, even if some of its channels are in use.
