- support for berlin GPUs
- major ring handling cleanup
- remove the old 3D blit code for bo moves in favor of CP DMA or sDMA
- lots of bug fixes

GEM does already a good job in tracking access to gem buffers via handles
and drm_vma access management. However, TTM drivers currently do not
verify this during mmap().
TTM provides the verify_access() callback to test this. So fix all drivers
to actually call into gem+vma to verify access instead of always returning
0.
All drivers assume that user-space can only get access to TTM buffers via
GEM handles. So whenever the verify_access() callback is called from
ttm_bo_mmap(), the buffer must have a valid embedded gem object. This is
true for all TTM+GEM drivers. But that's why this patch doesn't touch pure
TTM drivers (ie, vmwgfx).
v2: Switch to drm_vma_node_verify_access() to correctly return -EACCES if
access was denied.

gem_bo->driver_private is never read by mgag200 nor DRM core. No need to
set it. Besides, drm core clears it during setup, anyway.

When a BO gets pinned the placement may get changed. If the memory is
mapped into user space and user space has already accessed the mapped
range the page tables are set up but now point to the wrong memory.
Set bo.mdev->dev_mapping in mgag200_bo_create() to make sure that
ttm_bo_unmap_virtual() called from ttm_bo_handle_move_mem() will take
care of this.
v2: Don't call ttm_bo_unmap_virtual() in mgag200_bo_pin(), fix comment.

This replaces drm_mtrr_{add,del} with arch_phys_wc_{add,del}. The
interface is simplified (because the base and size parameters to
drm_mtrr_del never did anything), and it no longer adds MTRRs on
systems that don't need them.

On F19 testing, it was noticed we get a lot of errors in dmesg
about being unable to reserve the buffer when plymouth starts,
this is due to the buffer being in the process of migrating,
so it makes sense we can't reserve it.
In order to deal with it, this adds delayed updates for the dirty
updates, when the bo is unreservable, in the normal console case
this shouldn't ever happen, its just when plymouth or X is
pushing the console bo to system memory.

All items on the lru list are always reservable, so this is a stupid
thing to keep. Not only that, it is used in a way which would
guarantee deadlocks if it were ever to be set to block on reserve.
This is a lot of churn, but mostly because of the removal of the
argument which can be nested arbitrarily deeply in many places.
No change of code in this patch except removal of the no_wait_reserve
argument, the previous patch removed the use of no_wait_reserve.
v2:
- Warn if -EBUSY is returned on reservation, all objects on the list
should be reservable. Adjusted patch slightly due to conflicts.
v3:
- Focus on no_wait_reserve removal only.

This is a driver for the G200 server engines chips,
it doesn't driver any of the Matrix G series desktop cards.
It will bind to G200 SE A,B, G200EV, G200WB, G200EH and G200ER cards.
Its based on previous work done my Matthew Garrett but remodelled
to follow the same style and flow as the AST server driver. It also
works along the same lines as the AST server driver wrt memory management.
There is no userspace driver planned, xf86-video-modesetting should be used.
It also appears these GPUs have no ARGB hw cursors.
v2: add missing tagfifo reset + G200 SE memory bw setup pieces.
