[PATCH 6.6.y 1/3] drm/gpuvm: rename struct drm_gpuva_manager to struct drm_gpuvm

[Sasha Levin <sashal@kernel.org>]

From: Danilo Krummrich <dakr@redhat.com>

[ Upstream commit f72c2db47080523d5e0f3c20846c96ed31c35648 ]

Rename struct drm_gpuva_manager to struct drm_gpuvm including
corresponding functions. This way the GPUVA manager's structures align
very well with the documentation of VM_BIND [1] and VM_BIND locking [2].

It also provides a better foundation for the naming of data structures
and functions introduced for implementing a common dma-resv per GPU-VM
including tracking of external and evicted objects in subsequent
patches.
