We now have bo->page_alignment which perfectly describes what we need if
we have min page size restrictions for lmem. We can also drop the flag
here, since this is the default behaviour for all objects.
v2(Thomas):
- bo->page_alignment is in page units

Move back to the buddy allocator for managing device local memory, and
restore the lost mock selftests. Keep around the range manager related
bits, since we likely need this for managing stolen at some point. For
stolen we also don't need to reserve anything so no need to support a
generic reserve
Now that ttm_resource_manager just returns a generic ttm_resource we
don't need to reference the mm_node stuff anymore which mostly only
makes sense for drm_mm_node. In the next few patches we want switch over
to the ttm_buddy_man which is just another type of ttm_resource so
reflect that in the na
Currently we just ignore the I915_BO_ALLOC_CONTIGUOUS flag, which is
fine since everything is already contiguous with the ttm range manager.
However in the next patch we want to switch over to the ttm buddy
manager, where allocations are by default not contiguous.

Instead of relying on a static placement, calculate at get_pages() time.
This should work for LMEM regions and system for now. For stolen we need
to take preallocated range into account. That well be added later.

Add back our standalone i915_buddy allocator and integrate it into a
ttm_resource_manager. This will plug into our ttm backend for managing
device local-memory in the next couple of patches.
v2(Thomas):
- Return -ENOSPC from the buddy; ttm expects this in order to
trigger eviction
-
We need to be able to build an sg table from our list of buddy blocks,
so that we can later plug this into our ttm backend, and replace our use
of the range manager.

New KMS properties come with a bunch of requirements to avoid each
driver from running their own, inconsistent, set of properties,
eventually leading to issues like property conflicts, inconsistencies
between drivers and semantics, etc.
Let's document what we expect.

The drm_connector detect, drm_dp_aux transfer and mipi_dsi_host
operations typically require to access their underlying device to
perform what is expected of them.
However, there's no guarantee on the fact that the device has been
enabled through atomic_enable or similar that will usually power th
Drivers that allow concurrent access over multiple DP channels need to
provide additional locking, even though the hw_mutex field might
indicate otherwise. Clarify it in the documentation.
