Add some new interfaces for ACRN hypervisor HSM driver:
- MMIO device passthrough
- virtual device creating/destroying
- platform information fetching from the hypervisor
ChangeLog:
v3:
- remove "platform information fetching from the hypervisor". What platform
information needs to be fetched has not been finally decided. Will send tis
patch out once that has been decided.
- add comments where is the userspace code that uses this new api:
- MMIO device passthrough
(a) assign a MMIO device to a User VM
https://github.com/projectacrn/acrn-hypervisor/blob/master/devicemodel/core/vmmapi.c#L562
(b) de-assign a MMIO device from a User VM
https://github.com/projectacrn/acrn-hypervisor/blob/master/devicemodel/core/vmmapi.c#L568
- virtual device creating/destroying
(a) create a virtual device for a User VM
https://github.com/projectacrn/acrn-hypervisor/blob/master/devicemodel/core/vmmapi.c#L606
(b) destroy a virtual device of a User VM
https://github.com/projectacrn/acrn-hypervisor/blob/master/devicemodel/core/vmmapi.c#L612
v2:
- remove "[email protected]" in the cc list since this patch set
doesn't fix any anything, it's not for Linux -stable releases.

"RFC" means that you do not feel good about having these merged. What
needs to be finished before you send a "real" set of patches that you
want to have reviewed properly?
thanks,
