8caf8427f8 dma/dpaa2: introduce driver skeleton
The DPAA2 DMA  driver is an implementation of the dmadev APIs,
that provide means to initiate a DMA transaction from CPU.
Earlier this was part of RAW driver, but with DMA drivers
added as separate flavor of drivers, this driver is being
moved to DMA drivers.

583f373297 dma/dpaa: introduce DPAA DMA driver skeleton
The DPAA DMA  driver is an implementation of the dmadev APIs,
that provide means to initiate a DMA transaction from CPU.
The initiated DMA is performed without CPU being involved
in the actual DMA transaction. This is achieved via using
the QDMA controller of DPAA SoC.

05d5fc66a2 dma/skeleton: introduce skeleton driver
Skeleton dmadevice driver, on the lines of rawdev skeleton, is for
showcasing of the dmadev library.

Design of skeleton involves a virtual device which is plugged into VDEV
bus on initialization.

Also, enable compilation of dmadev skeleton drivers.
