drivers should ensure that tasklets are killed, so that they can't be
executed after driver remove is executed, so ensure they are killed.This driver used vchan tasklets, so those need to be killed.

Pull slave-dmaengine updates from Vinod Koul:
- new drivers for:
- Ingenic JZ4780 controller
- APM X-Gene controller
- Freescale RaidEngine device
- Renesas USB Controller- remove device_alloc_chan_resources dummy handlers
- sh driver cleanups for peri peri and related emmc and asoc patches
as well- fixes and enhancements spread over the drivers

There is no need to init .owner field.
Based on the patch from Peter Griffin
"mmc: remove .owner field for drivers using module_platform_driver"This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."Signed-off-by: Kiran Padwal

chanctnt is already filled by dma_async_device_register, which uses the channel
list to know how much channels there is.Since it's already filled, we can safely remove it from the drivers' probe
function.Signed-off-by: Maxime Ripard

Now that all users of the custom jz4740 DMA API have been converted to use
the dmaengine API instead we can remove the custom API and move all the code

This patch adds dmaengine support for the JZ4740 DMA controller. For now the
driver will be a wrapper around the custom JZ4740 DMA API. Once all users of the
custom JZ4740 DMA API have been converted to the dmaengine API the custom API
will be removed and direct hardware access will be added to the dmaengine
driver.Signed-off-by: Lars-Peter Clausen
