Subject: drm/vmwgfx: switch to own vma manager

Git-commit: 293f86b365ad678dd89b61caa11b67270cc542a0
Patch-mainline: v5.5-rc1
References: bsc#1152489

Add struct drm_vma_offset_manager to vma_private, initialize it and
pass it to ttm_bo_device_init().

With this in place the last user of ttm's embedded vma offset manager
is gone and we can remove it (in a separate patch).
