Drop use of the deprecated drmP.h header.
While touching the files divide include files in blocks
and sort the files alphabetically.
v2:
- Replace all uses of DRM_WAIT_ON() with VIA_WAIT_ON()
and thus avoiding to pull in drm_os_linux.h
v3:
- DRM_WAIT_ON replacement moved to earlier patch (Emil)

The drm_mm range manager claimed to support top-down insertion, but it
was neither searching for the top-most hole that could fit the
allocation request nor fitting the request to the hole correctly.
In order to search the range efficiently, we create a secondary index
for the holes using either their size or their address. This index
allows us to find the smallest hole or the hole at the bottom or top of
the range efficiently, whilst keeping the hole stack to rapidly service
evictions.
v2: Search for holes both high and low. Rename flags to mode.
v3: Discover rb_entry_safe() and use it!
v4: Kerneldoc for enum drm_mm_insert_mode.

There can only be one current master, and it's for the overall device.
Render/control minors don't support master-based auth at all.
This simplifies the master logic a lot, at least in my eyes: All these
additional pointer chases are just confusing.
While doing the conversion I spotted some locking fail:
- drm_lock/drm_auth check dev->master without holding the
master_mutex. This is fallout from

drm: Protect the master management with a drm_device::master_mutex v3
but I honestly don't care one bit about those old legacy drivers
using this.
- debugfs name info should just grab master_mutex.
- And the fbdev helper looked at it to figure out whether someone is
using KMS. We just need a consistent value, so READ_ONCE. Aside: We
should probably check if anyone has opened a control node too, but I
guess current userspace doesn't really do that yet.
v2: Balance locking, reported by Julia.
v3: Rebase on top of Chris' oops fixes.

The context_dtor callback is only called once we've successfully loaded
the driver, which means dev->dev_private is set up. The check is hence
pointless.
Also dev->dev_private is deref already above, so compilers are free
to elide it anyway.

Add a "best_match" flag similar to the drm_mm_search_*() helpers so we
can convert TTM to use them in follow up patches. We can also inline the
non-generic helpers and move them into the header to allow compile-time
optimizations.
To make calls to drm_mm_{search,insert}_node() more readable, this
converts the boolean argument to a flagset. There are pending patches that
add additional flags for top-down allocators and more.
v2:
- use flag parameter instead of boolean "best_match"
- convert *_search_free() helpers to also use flags argument

A few things
- kill reclaim_buffers, it's never ever called because via does not set
DRIVER_HAVE_DMA
- inline the idlelock dance into the buffer reclaim logic and make it
a simple preclose cleanup function
- directly call the the dma_quiescent function and kill the needless
if check.
v2: Actually drop the idlelock when we take it. Reported by James
Simmons.
v3: Rebased onto latest drm-next.
v4: Fixup the refactor.
v5: More fixup the refactor - I've accidentally changed the check for
any master to checking whether the closing fd is the master.
v6: Don't forget to drop the idlelock in the early return path, too.

To make the transition in a piece-wise and bisectable way possible,
I've hijacked the ->owner_list from drm_sman. While transitioning, the
list_add was done by the driver, while the list_del was still done by
the dying sman code.
Now that we are in full control of ->owner_list, do the list_del
ourselves.
v2: Better explain the list_del trickery as suggested by Chris Wilson.

In contrast to kms drivers, sis/via _always_ associated a buffer with
a drm fd. So by the time we reach lastclose, all open drm fds are gone
and with them their associated objects.
So when sis/via call drm_sman_cleanup in their lastclose funcs, that
will free 0 objects.
The owner tracking now serves no purpose at all, hence rip it ou. We
can't kill the corresponding fields in struct drm_memblock_item yet
because we hijack these in the new driver private owner tracking. But
now that drm_sman.c doesn't touch ->owner_list anymore, we need to
kill the list_move hack and properly add the item to the file_priv
list.
Also leave the list_del(&obj->owner_list) in drm_sman_free for the
moment, it will move to the drivers when sman disappears completely.
v2: Remove the redundant INIT_LIST_HEAD as noted by Chris Wilson

With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.
This restructures the drm along the lines of other kernel components.
It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.
