Subject: [PATCH v2 00/17] vdpa: generalize vdpa simulator

This series moves the network device simulator in a new module
(vdpa_sim_net) and leaves the generic functions in the vdpa_sim core
module, allowing the possibility to add new vDPA device simulators.

For now I removed the vdpa-blk simulator patches, since I'm still working
on them and debugging the iotlb issues.

Thanks to Max that started this work! I took his patches and extended a bit.

As Jason suggested, I simplified the "vdpa: split vdpasim to core and
net modules" patch, moving some changes out in small patches.
@Max: I put your Co-developed-by and Signed-off-by tags on these patches,
let me know if it is okay for you, or if there is a better way to give
credit to your work!

v1: https://lists.linuxfoundation.org/pipermail/virtualization/2020-November/050677.html

v2:
  - moved most of the patches before the vdpa-core/net split [Jason]
  - removed unnecessary headers
  - removed 'default n' in Kconfig entries [Jason]
  - added VDPASIM_IOTLB_LIMIT macro [Jason]
  - set vringh notify callback [Jason]
  - used VIRTIO terminology for in_iov/out_iov [Stefan]
  - simplified "vdpa: split vdpasim to core and net modules" patch,
    moving some changes out in small patches
  - left batch_mapping module parameter in the core [Jason]
