Add a dummy PMU device so the PMU falcon is instanciated and can be used
by secure boot.
We could reuse gk20a's implementation here, but it would fight with
secboot over PMU falcon's ownership and secboot will reset the PMU,
preventing it from operating afterwards. Proper handout between secboot
and pmu is coming along with the actual gm20b PMU implementation, so
use this as a temporary solution.

Falcon processors are used in various places of GPU chips. Although there
exist different versions of the falcon, and some variants exist, the
base set of actions performed on them is the same, which results in lots
of duplicated code.
This patch consolidates the current nvkm_falcon structure and extends it
with the following features:
* Ability for an engine to obtain and later release a given falcon,
* Abstractions for basic operations (IMEM/DMEM access, start, etc)
* Abstractions for secure operations if a falcon is secure
Abstractions make it easy to e.g. start a falcon, without having to care
about its details. For instance, falcons in secure mode need to be
started by writing to a different register.
Right now the abstractions variants only cover secure vs. non-secure
falcon, but more will come as e.g. SEC2 support is added.
This is still a WIP as other functions previously done by
engine/falcon.c need to be reimplemented. However this first step allows
to keep things simple and to discuss basic design.

Let's disable all scaling that requires horizontal decimation with
higher factor than 4, until we have better estimates of what we can
and can not do. However, NV12 color format appears to work Ok with
all decimation factors.
When decimating horizontally by more that 4 the dss is not able to
fetch the data in burst mode. When this happens it is hard to tell if
there enough bandwidth. Despite what theory says this appears to be
true also for 16-bit color formats.

commit f2d580b9a8
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date: Wed May 4 14:38:26 2016 +0200
drm/core: Do not preserve framebuffer on rmfb, v4.
This introduces a slight behavioral change to rmfb. Instead of
disabling a crtc when the primary plane is disabled, we try to
preserve it.
Apart from old versions of the vmwgfx xorg driver, there is
nothing depending on rmfb disabling a crtc. Since vmwgfx is
a legacy driver we can safely only disable the plane with atomic.
If this commit is rejected by the driver then we will still fall
back to the old behavior and turn off the crtc.
v2:
- Remove plane->fb assignment, done by drm_atomic_clean_old_fb.
- Add WARN_ON when atomic_remove_fb fails.
- Always call drm_atomic_state_put.
v3:
- Use drm_drv_uses_atomic_modeset
- Handle the case where the first plane-disable-only commit fails
with -EINVAL. Some drivers do not support this, fall back to
disabling all crtc's in this case.

The API is not suitable for subsystems consisting of multiple devices
and requires severe hacks to use it. To mitigate this, this patch
implements allocation and address space management locally by using
helpers provided by DRM framework, like other DRM drivers do, e.g.
Tegra.
This patch should not introduce any functional changes until the driver
is made to attach subdevices into an IOMMU domain with the generic IOMMU
API, which will happen in following patch. Based heavily on GEM
implementation of Tegra DRM driver.
