gpu: nvgpu: support userspace vidmem mappings
When mapping a userspace buffer, determine if it was vidmem allocated
from the aperture of the current gpu, and pass that information into
page tables.
Mapping a vidmem buffer to a gpu it wasn't allocated from is disallowed.
This includes mapping vidmem to igpus and to possibly other dgpus on the
system.
