In case of msm drm bind failure, pm runtime put sync
is called from dsi driver which issues an asynchronous
put on mdss device. Subsequently when dpu_mdss_destroy
is triggered the change will make sure to put the mdss
device in suspend and clearing pending work if not
scheduled.

Do some debugfs cleanups from across the DPU driver. The DRM
destroy functions will do a recursive delete on the entire
debugfs node so there is no need to store dentry pointers for
the debugfs files that are persistent for the life of the
driver. This also means that the destroy functions can go
away too.
Also, use standard API functions where applicable instead of
using hand written code.
v3: No changes
v2: Add more code; most of the dpu debugfs files should be
addressed now.

Instead of assigning/clearing the crtc on vblank enable/disable, we can
just assign and clear the crtc on modeset. That allows us to just toggle
the encoder's vblank interrupts on vblank_enable.
So why is this important? Previously the driver was using the legacy
pointers to assign/clear the crtc. Legacy pointers are cleared _after_
disabling the hardware, so the legacy pointer was valid during
vblank_disable, but that's not something we should rely on.
Instead of relying on the core ordering the legacy pointer assignments
just so, we'll assign the crtc in dpu_crtc enable/disable. This is the
only place that mapping can change, so we're covered there.
We're also taking advantage of drm_crtc_vblank_on/off. By using this, we
ensure that vblank_enable/disable can never be called while the crtc is
off (which means the assigned crtc will always be valid). As such, we
don't need to use modeset locks or the crtc_lock in the
vblank_enable/disable routine to be sure state is consistent.
...I think.

The indirection of registering a callback and opaque pointer isn't reall
useful when there's only one callsite. So instead of having the
vblank_cb registration, just give encoder a crtc and let it directly
call the vblank handler.
In a later patch, we'll make use of this further.

I think the intention here was to protect the enc->crtc access, but
that's insufficient to avoid enc->crtc changing. Fortunately we're
already holding the modeset lock when this is called (from
atomic_check), so remove the crtc_lock and add a modeset lock check.
While we're at it, use the encoder mask from crtc state instead of
legacy pointer.

There are 4 times that _dpu_crtc_vblank_enable_no_lock() is called:
1- crtc enable
2- crtc disable
3- crtc vblank enable
4- crtc vblank disable
When we enable or disable the crtc, we call drm_crtc_vblank_on and
drm_crtc_vblank_off respectively. That will gate vblank enables and
disables to only being called when the crtc is active. That means that
we can just enable/disable pm runtime in crtc enable/disable. This will
be beneficial in trying to eliminate blocking calls from the vblank call
chain.

The crtc runtime resume doesn't actually operate on the crtc, but rather
its encoders. The problem with this is that we need to inspect the crtc
state to get the currently connected encoders. Since runtime resume
isn't guaranteed to be called while holding the modeset locks (although
it sometimes is), this presents a race condition.
Now that we have ->enabled on the virtual encoders, and a lock to
protect it, just call resume on each encoder and only restore the ones
that are enabled.

This patch allows using drm/msm without qcom display hardware. It adds a
amd,imageon compatible, which is used instead of qcom,adreno, but does
not require a top level msm node.

A2XX has its own very simple MMU.
Added a msm_use_mmu() function because we can't rely on iommu_present to
decide to use MMU or not.

When trying to get the display up on my sdm845 board I noticed that
the display wouldn't probe if I had the dsi1 node marked as "disabled"
even though my board doesn't use dsi1. It looks like the msm code
adds all nodes to its list of components even if they are disabled. I
believe this doesn't work because all registered components need to
come up before we finish probing. Let's do like other DRM code and
only add available components.

This patch sprinkles a few async/legacy_cursor_update checks
through commit to ensure that cursor updates aren't blocked on vsync.
There are 2 main components to this, the first is that we don't want to
wait_for_commit_done in msm_atomic before returning from atomic_complete.
The second is that in dpu we don't want to wait for frame_done events when
updating the cursor.
Changes in v2:
- None

There exists a case where a flush of a plane/dma may have been triggered
& started from an async commit. If that plane/dma is subsequently disabled
by the next commit, the flush register will continue to hold the flush
bit for the disabled plane. Since the bit remains active,
pending_kickoff_cnt will never decrement and we'll miss frame_done
events.
This patch limits the check of flush_register to include only those bits
which have been updated with the latest commit.

In case of msm drm bind failure, dpu_mdss_destroy is triggered.
In this function, resources are freed and pm runtime disable is
called, which triggers dpu_mdss_disable. Now in dpu_mdss_disable,
driver tries to access a memory which is already freed. This
results in kernel panic. Fix this by ensuring proper sequence
of dpu destroy and disable calls.
