[PATCH] rust: drm: gpuvm: update DriverGpuVm for DeviceContext

[Deborah Brouwer]

Since the introduction of DeviceContext, there is no longer a single
driver object type to equate with the GPUVM object type.

Instead of threading DeviceContext through GPUVM, remove the strict
identity between DriverGpuVm::Object and drm::Driver::Object and
instead tighten the requirement that the DriverGpuVm::Object be an
allocatable GEM object associated with the same DRM driver.

Also, make GpuVm::new() generic over DeviceContext so it can accept a
drm::Device<T::Driver, Ctx>.
