v4 -> v5:
- add Arnd's R-b
v3 -> v4:
- pass reset to vfio_platform_unregister_reset
v2 -> v3:
- use vfio_platform_register_reset macro
v1 -> v2:
- remove vfio_platform_reset_private.h and move back the macro to
vfio_platform_private.h header: removed reset_module_register &
unregister (symbol_get)
- defines the module_vfio_reset_handler macro as suggested by Arnd
(formerly in vfio_platform_reset_private.h)
