nouveau_chan.device is always the same as nouveau_chan.cli.device,
so there's no need to store it separately.

These are some dodgy "convenience" macros for the DRM driver to peek
into NVKM state. They're still used in a few places, but don't belong
in nvif/device.h in any case.
Move them to nouveau_drv.h, and modify callers to pass a nouveau_drm
instead of an nvif_device.
v2:
- use drm->nvkm pointer for nvxx_*() macros, removing some void*
v3:
- add some explanation of the nvxx_*() macros

There's no good reason the ioremap() that results from nvif_object_map()
should fail, so add a check that the map succeeded, and remove the rd/wr
methods from display channel objects.
As this was the last user of rd/wr methods, the nvif plumbing is removed
at the same time.

The next commit removes the nvif rd/wr methods from nvif_device, which
were probably a bad idea, and mostly intended as a fallback if ioremap()
failed (or wasn't available, as was the case in some tools I once used).
The nv04 KMS driver already mapped the device, because it's mostly been
kept alive on life-support for many years and still directly bashes PRI
a lot for modesetting.
Post-nv50, I tried pretty hard to keep PRI accesses out of the DRM code,
but there's still a few random places where we do, and those were using
the rd/wr paths prior to this commit.
This allocates and maps a new nvif_device (which will replace the usage
of nouveau_drm.master.device later on), and replicates this pointer to
all other possible users.
This will be cleaned up by the end of another patch series, after it's
been made safe to do so.

nouveau_usif.c was already stripped right back a couple of years ago,
limiting what userspace could do with it.
A follow-on series removes the nvkm side of these interfaces entirely,
in order to make it less of a nightmare to add/change internal APIs in
the future.
Unfortunately. Userspace uses some of this.
Fortunately, userspace only ever ended up using a fraction of the APIs,
so those are reimplemened here in a more direct manner, and return
-EINVAL to userspace for everything else.

drm->master isn't really a nouveau_cli, and is mostly just used to get
at an nvif_mmu object to implement a hack around issues with the ioctl
interface to nvkm.
Later patches in this series allocate nvif_device/mmu objects in
nouveau_drm directly, removing the need for master.
A pending series to remove the "ioctl" layer between DRM and NVKM
removes the need for the above-mentioned hack entirely.
The only other member of drm->master that's needed is the nvif_client,
and is a dependency of device/mmu. So the first step is to move its
allocation out of code handling nouveau_cli init.
v2:
- modified slightly due to the addition of tegra/pci cleanup patches
v3:
- move nvif init below drm_dev_alloc() to avoid changing nouveau_name()

There's various different places in the drm code that get at the
nvkm_device via various creative (and not very type-safe) means.
One of those being via nvif_device.object.priv.
Another patch series is going to entirely remove the ioctl-like
interfaces beween the drm code and nvkm, and that field will no
longer exist.
This provides a safer replacement for accessing the nvkm_device,
and will used more in upcoming patches to cleanup other cases.

This was basically just another one of amdgpus hacks. The parameter
allowed to restart the scheduler without turning fence signaling on
again.
That this is absolutely not a good idea should be obvious by now since
the fences will then just sit there and never signal.
While at it cleanup the code a bit.

nouveau_sched_init() uses the function drm_sched_init(). The latter
function has parameters called "hang_limit" and "timeout" in its API
documentation.
nouveau_sched_init(), however, defines a variable called
"job_hang_limit" which is passed to drm_sched_init()'s "timeout"
parameter. The actual "hang_limit" parameter is directly set to 0.
Rename "job_hang_limit" to "timeout".

The exynos-next pull is based on a newer -rc than drm-next. hence
backmerge first to make sure the unrelated conflicts we accumulated
don't end up randomly in the exynos merge pull, but are separated out.
Conflicts are all benign: Adjacent changes in amdgpu and fbdev-dma
code, and cherry-pick conflict in xe.

In nouveau_connector_get_modes(), the return value of drm_mode_duplicate()
is assigned to mode, which will lead to a possible NULL pointer
dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.

"struct nouveau_job_ops" is not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increase overall security.
In order to do it, "struct nouveau_job" and "struct nouveau_job_args" also
need to be adjusted to this new const qualifier.

I'm pretty sure this optimisation is actually not a great idea,
and is racy with other things waiting for fences.
Just nuke it, there should be no need to do fence waits in a
busy CPU loop.

If the card doesn't have display hardware, hpd_work and hpd_lock are
left uninitialized which causes BUG when attempting to schedule hpd_work
on runtime PM resume.
Fix it by adding headless flag to DRM and skip any hpd if it's set.
