v2:
- Fixed "warning: variable 'dev' is used uninitialized" reported by
'kernel test robot' and Dan Carpenter
- rebased on top of other changes (dev_attr, get_config(), notify(), etc.)
- left batch_mapping module parameter in the core [Jason]
v1:
- Removed unused headers
- Removed empty module_init() module_exit()
- Moved vdpasim_is_little_endian() in vdpa_sim.h
- Moved vdpasim16_to_cpu/cpu_to_vdpasim16() in vdpa_sim.h
- Added vdpasim*_to_cpu/cpu_to_vdpasim*() also for 32 and 64
- Replaced 'select VDPA_SIM' with 'depends on VDPA_SIM' since selected
option can not depend on other [Jason]

Looks good, consider there are some still some questions left. I will
probably ack for the next version.
Thanks
