The only event function that is called from IRQ context is event_free,
which is already using atomic bitmap operations, so we can avoid taking
the event spinlock in this function completely. As other the other
functions still using the event spinlock are all called from normal
process context, we can avoid disabling IRQs while holding the spinlock.

v2: Removed leftover debug printouts
This time around, seeing some love for some older hw:
- a2xx gpu support for apq8060 (hp touchpad) and imx5 (headless
gpu-only mode)
- a2xx gpummu support (a2xx was pre-iommu)
- mdp4 display support for apq8060/touchpad
For display/dpu:
- a big pile of continuing dpu fixes and cleanups
On the gpu side of things:
- per-submit statistics and traceevents for better profiling
- a6xx crashdump support
- decouple get_iova() and page pinning.. so we can unpin from
physical memory inactive bo's while using softpin to lower
cpu overhead
- new interface to set debug names on GEM BOs and debugfs
output improvements
- additional submit flag to indicate buffers that are used
to dump (so $debugfs/rd cmdstream dumping is useful with
softpin + state-objects)

Mostly just initial support for Turing TU104/TU106 chipsets. Support
for TU102 is missing as I don't yet have HW, but it should be trivial
to add in later in the merge window (in theory).
It's a bit of a rough first pass that'll get improved in future
releases as a finish figuring out some of the other HW changes, but
it's good enough as it stands for modesetting and suspend/resume etc.
Acceleration bring-up is incomplete due to NVIDIA not yet having
provided FW images for me to use, though command submission and copy
engines are functional already.

These changes contain a couple of minor fixes for host1x and the Falcon

finally enable support for host1x, VIC and display on Tegra194. I've
also added a patch that enables audio over HDMI using the SOR which has
been tested, and works, on both Tegra186 and Tegra194.

[Why]
Legacy cursor plane updates from drm helpers go through the full
atomic codepath. A high volume of cursor updates through this slow
code path can cause subsequent page-flips to skip vblank intervals
since each individual update is slow.
This problem is particularly noticeable for the compton compositor.
[How]
A fast path for cursor plane updates is added by using DRM asynchronous
commit support provided by async_check and async_update. These don't do
a full state/flip_done dependency stall and they don't block other
commit work.
However, DC still expects itself to be single-threaded for anything
that can issue register writes. Screen corruption or hangs can occur
if write sequences overlap. Every call that potentially perform
register writes needs to be guarded for asynchronous updates to work.
The dc_lock mutex was added for this.

[Why]
These properties aren't being carried over when the atomic state.
This tricks atomic check and commit tail into performing underscan
and scaling operations when they aren't needed.
With the patch that forced scaling/RMX_ASPECT on by default this
results in many unnecessary surface updates and hangs under certain
conditions.
[How]
Duplicate the properties.
