v2:
- rebased on top of other changes (dev_attr, get_config(), notify(), etc.)
- memset to 0 the config structure in vdpasim_blk_get_config()
- used vdpasim pointer in vdpasim_blk_get_config()
v1:
- Removed unused headers
- Used cpu_to_vdpasim*() to store config fields
- Replaced 'select VDPA_SIM' with 'depends on VDPA_SIM' since selected
