fbef403aa7 dmaengine: moxart-dma: Fix memory leak when stopping a running transfer
The vd->node is removed from the lists when the transfer started so the
vchan_get_all_descriptors() will not find it. This results memory leak.

ac850cc7da dmaengine: moxart: Split device_control
Split the device_control callback of the Moxart DMA driver to make use of the
newly introduced callbacks, that will eventually be used to retrieve slave
capabilities.

55f04d7f59 dma: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

5f9e685a0d dmaengine: Add MOXA ART DMA engine driver
The MOXA ART SoC has a DMA controller capable of offloading expensive
memory operations, such as large copies. This patch adds support for
the controller including four channels. Two of these are used to
handle MMC copy on the UC-7112-LX hardware. The remaining two can be
used in a future audio driver or client application.
