Some APU devices are behind an IOMMU.
For some of these devices, we can't use DMA API because
they use static addresses so we have to manually use
IOMMU API to correctly map the buffers.
This adds support of IOMMU.

This implements a driver to use with a simulation APU.
This is useful for testing purpose and can be used as a basis to
implement real platform driver.
Communication between the simulated APU and the driver is done
using netlink socket.

to queue and dequeue requests.
This uses DRM scheduler to manage the requests.
The requests allocation and send and receive operations
