In order to simplify the code of the vdpa_sim core, we move the
config management in each device simulator.
The device must provide the size of config structure and a callback
to update this structure called during the vdpasim_set_features().
Similarly, I suggest to do this before patch 2, then there's no need for
the conversion of blk device.

Let's use set_config/get_config to align with virtio/vhost.
Other looks good.
Thanks
