[WHY]
For DCN31 onward, LTTPR is to be enabled and set to Transparent by

In amdgpu_fence_driver_hw_fini, no need to call drm_sched_fini to stop
scheduler in s3 test, otherwise, fence related failure will arrive
after resume. To fix this and for a better clean up, move drm_sched_fini
from fence_hw_fini to fence_sw_fini, as it's part of driver shutdown, and
should never be called in hw_fini.

v2: rename amdgpu_fence_driver_init to amdgpu_fence_driver_sw_init,
to keep sw_init and sw_fini paired.

If one GTT BO has been evicted/swapped out, it should sit in CPU domain.
TTM only alloc struct ttm_resource instead of struct ttm_range_mgr_node
for sysMem.

Now when we update mapping for such invalidated BOs, we might walk out
of bounds of struct ttm_resource.

Three possible fix:
1) Let sysMem manager alloc struct ttm_range_mgr_node, like
ttm_range_manager does.
2) Pass pages_addr to update_mapping function too, but need memset
pages_addr[] to zero when unpopulate.
3) Init amdgpu_res_cursor directly.

It turns out that these variables are also passed through the hdmi codec

if it's used multiple times use a variable to store it instead of
dereferencing it every time.

We make the following changes to the documentation of drm leases to
make it easier to reason about their usage. In particular, we clarify
the lifetime and locking rules of lease fields in drm_master:

1. Make it clear that &drm_device.mode_config.idr_mutex protects the
lease idr and list structures for drm_master. The lessor field itself
doesn't need to be protected as it doesn't change after it's set in
drm_lease_create.

2. Add descriptions for the lifetime of lessors and leases.

3. Add an overview DOC: section in drm-uapi.rst that defines the
terminology for drm leasing, and explains how leases work and why
they're used.
