Define UAPI for Shared Virtual Memory (SVM) fucntionality including
SVM capability and configurability.
When there is no GPU page fault support available, add ioctls
to explicitly bind and migrate virtual address ranges.

Having this as a separate commit ahead of the functionality breaks
bisecting.

The uAPI should be exposed in similar sized chunks as it's implemented.
If it has to go in as single patch, that should be after all the
plumbing is already in place.

That also gives a clear indication to anybody backporting that you
need to backport until the uAPI patch.


Ok, will include ioctls in the relavant patches instead of this separate patch.

Thanks,
Niranjana
